I know that it happens but I as well as lots of other bowlers consider it "wrong".
If you are a scratch bowler in that league (granted - using 240 as the hdcp base pretty much means everyone gets hdcp but it can happen) you cannot bowl more than 300.
And even so, still if you are averaging 230 in the league, you only get 9 pins of hdcp so your maximum score if uncapped is 309. So in the example from above, you score the maximum you can and you still lose?
?? 309 to 311 or 309 to 315.
I have run hdcp brackets in leagues for over 10+ years, and I state it up front. Max score is 300 (including hdcp). Don't like it, don't enter.
WORSE CASE SCENARIO, IF YOU BOWL A PERFECT GAME IN ANY MATCH PLAY LEAGUE OR BRACKET, IT SHOULD BE A TIE.
rant over... LOL
