I would say those jumps seem pretty correct..
but...
Strip , clean, and put the oil down like they did in the 70''s and I bet no one will average 240 or 220...
Yes the bowling ball technology helps a ton.. balls will hook harder off the dry.. and that dry doesn''t need to be as dry as it did in the 70''s ...So yes.. balls will hook more in oil than they did in the 70''s and 80''s..
but the oil pattern rules all.. there are patterns that can be put down that will keep most anyone from breaking 210 on a consistant basis.
precisely metered and placed oil in a high scoring configuration and clean backends is what creates high scores.
