One week ago, I threw what looked like a good strike ball and ended up with a contrapted 7-10 split! The 8 pin slid into the 7 pin spot! I had never seen anything like that before and was sure that I would never see it again. But, TODAY, I threw another, decent, strike shot, it was coming in a little light and after about 60 feet of ball displacement, I couldn't believe my eyes. The 5 pin slid all the way into the 7 pin spot! Not out-of-range or anything. A perfectly manufactured 7-10 split! Of course, on both shots I left the 10 pin, but that goes without saying. What surprised me was that these other pins slid as far as they did without tipping over(I have seen small slides resulting in out-of-ranges).
I told the MOS and he said that he wasn't surprised! That when the backends only get stripped every 2-3 days that carrydown will get to the pin deck and cause the pins to slide instead of tipping over.
Apparently, the new guy hadn't been using the machine properly on his few shifts a week and had not been stripping the backends while the MOS(and other mechanics) had been.
Anyone else had the luxury of bowling on lanes with cruddy pin decks?
