Well, we use the same thing on my monday nite league because guys would sandbag the first week or two, then shoot 600's or 700's for the next couple weeks, to case in using thier handicap.
So last yr was our first time using it too. But this yr, i noticed alot of guys doing the same, sandbaggin the first couple of weeks, to get thier handicap way up.
Anyways this team was the reason why we put this rule into action, because all of them are 190-215avg bowlers and they would intentionally shoot 150games the first week or two, so they would have handicap, and then out would come the 600's. And they even did it this yr too, the first week of the yr, they didnt have a series over 550.
But i also had a guy on my team for the past three yrs who would do the same, but i finally got rid of him THANK YOU GOD!!!!!!!! lol he was litterally a 240avg guy on any condition. And he would barely avg 200. And of course he was a lefty. so it was a double whammy.
And he would do this so he can go into Handicap tournaments with guys who have tons of handicap and do nothing but shoot 750 or 800. And his name is Nick Rodriguez,,, he lives in the West Michigan area, and is a lefty.
Now i know my average is going to be down, when my new average kicks in, in a week, unless i shoot about 700 tomorrow nite, but i have been running into total burn out in the third game where it doesnt matter what you do the ball just hooks early.
So for the first two weeks my third games have been 134 and 164, lol. yet my first two games are like 220's or better. But oh well, my other leagues i am all in the low 200's like normal. I am not a high 200avg person and probably never will be. I do have my streaks where i do nothing but shoot 670's or better for a few weeks, but i have had times where i had tough times shooting over 500 lol.
But yes there are guys out there who will do anything to get that lil bit of edge, but, i hate sandbaggers. But that is also why i dont bowl in anything but Scratch tournaments unless its our city tournament or State.
