Thankyou Robbie, but it seems we are still wrong though.

You are not trolling? Then I am sorry my friend but you really don't get it.

Take 100% of 200 for example.
If bowler A averages 150, his handicap is 50. He shoots a 200 game, his handicap score is 250.
Bowler B averages 190, his handicap is 10. He has to shoot +240 to win that game.
Now tell me, which is easier? A 150 average bowler shooting 200, or a 190 average bowler shooting 240?
At 100% of 200, the lower average bowler has the advantage... for what? Being a less capable bowler?

Now take 80% of 200 with the same scenario.
Bowler A averages 150. Handicap is then 40. He shoots a 200 game... handicap score is 240
Bowler B averages 190. Handicap is then 8. He has to shoot a 233 to win (rather than +240 in the above scenario).
Now what is more likely? 150 shooting 200, or 190 shooting 233?
This is 'fairer', but there should still be an incentive to improve as a bowler, and not simply rely on a favourable handicap system to keep you competitive.

And remember, if the league has multiple 200+ bowlers, we increase the scratch score to suit which also benefits the lower average bowler.

Come on now, its not that difficult to understand.

I agree with Robbie on this one, a higher average bowler is more likely to throw a 230-240 game than a 150 avg bowler throwing a 200. I have bowled a variety of leagues with various handicap, but any league where the maximum is below the highest averaging bowler, will generally always favour that higher average bowler, even bowled in a 100% of 200 league about 5 years back. Obviously this is the best example of a higher avg bowler having a head start based purely on their skill level.

The one point I would however like to make is that in the last few leagues I have participated in, the lane conditions have been fairly easy but not always so for my particular style (and no, I am not complaining about this, happy to cater for the majority), but when this occurs and the general league population have their league averages boosted, but still retain a significant handicap due to a generous handicap system, this is where the higher skilled or higher averaged bowlers starts to be disadvantaged, as not always easy to consistantly shoot 250+ plus games, but a 170-190 avg bowler that still has significant handicap can certainly bowl 220 plus games with not much hassle.

Another thing I have always found odd is that most leagues here in Newcastle do not permit a higher average bowler replacing a lower average player to sub for their league night, I can understand the principle but the reality is that the handicap system still stays in place and the substituting bowler if they were to normally play in that league would still have zero handicap.

I also agree with Rob, a handicap system should work as closely as possible to everyone being on equal footing.

It is, however, no rules have been broken that I can see.

Back to the topic.... Our handicap system is 90% of 230... They changed it to 230 because of one person. I did apologize to them.

[JWhitty]

It's not about breaking rules Androo, that's policing. I'm not having a dig, I just wanted the argument that seemed to be getting a little ruder and more personal to think about what they were saying.

We also use 90% of 230. We play singles (sports pattern) 6 per pair head to head (ie 1st per game gets 6, 2nd gets 5, 3rd gets 4 etc). We do this for scratch and handicap and keep separate standing sheets. Rarely do you get someone at the end of the season topping both but some have figured highly in both. I enjoy this format.

Now in both those cases if you have a bowler with a 230 league average in the league, if bowler A shoots his average he has either 200 or 190 therefore he gives away 30 or 40 pins start to the better bowler before they even walk on the lanes!!! Your bowler A might bowl a 200 game on a rare occasion, so what, he averages 150.

As you said, "Come on now, its not that difficult to understand."

Please read my whole post before commenting...

"And remember, if the league has multiple 200+ bowlers, we increase the scratch score to suit"

Clearly if you have 230 average bowlers, you don't set the scratch score at 200... or you apply negative handicaps as mentioned earlier.

Please move on, I have

Doesn't that and the next post by him "break the rules" by being irrelevant and off topic?

Now to the topic....

Correct me where I am wrong.
1. An average is what you are likely to bowl based on your previous performances. A 150 average bowler for example is likely to shoot games around the 150 mark, A 220 average bowler (while more than likely to be bowling at Mentone or some other ditch) will usually shoot around the 220 mark.
2. An average based on 80% of any upper limit that is greater than both of them will result in the 150 average bowler having a lower score should the two bowlers bowl to their usual ability.

There are a couple of points that come from this. First, there are probably not many 150 average bowlers at centres that lay a ditch (such as Keon, Mentone, Boronia and so on) and as such the scenario is unlikely to happen. Secondly, Rob is 100% correct when he says that anything other than 100% being used to calculate a handicap system will result in some inequality.

What other sport is there that allows people to be disadvantaged because they have less ability or experience?

I know I said I was over it , but I promise this will be my final post on the subject.

If you are at all interested, have a read of An Analysis of Bowling Scores and Handicap Systems

There is a lot of information here based on mathematic calculation and probability, but if you jump down to the results section you will read the following:

the individual handicap system of 80% of the difference between the bowler's average and a base figure of 225 is the fairest handicap system to use in league or tournament play.

They mention the 'Remington Rand study' in this study, which found the following:

The Remingtom Rand study[8] processed over 100,000 league bowling scores and the results suggested that the individual handicap system of 80% of the difference between the bowler's average and a base figure of 225 is the fairest handicap system.

I am making an assumption here, but I would imagine that at some point in time the powers that be also decided that 80% of X was the fairest system - I refer to the TBA rule book:

RULE 333 HANDICAP - (Unless covered by a Leagues own Rules)
The handicap allowance shall be 80 percent and shall be figured on the difference between each individuals average and 200 scratch.
e.g. If the average calculated = 134
For handicap calculation, 200 - 134 = 66
Handicap (80% of 66) = 52
The calculation results in 52.8. Decimal places are not used and are therefore ignored.

Now obviously this assumes that nobody in the league has an average higher than 200, but hopefully you get where I am coming from.

I stand by my comment that 100% of X favours the lower average bowler. I know that others will and do disagree, but I can live with that. I can also live with bowlrig not wanting to be my friend.
