First, thanks to each of you who take the time to support the BowlingChat.net forums. I've bowled and drilled since the early 70's but continue to learn and grow in our sport. This forum probably has the highest ratio of useful information versus, well not-so-useful information and posts, than any bowling-related forum/website I'm aware of.
Over recent years, I developed a bowling ball surface adjustment table in Excel to help my own understanding and gain clarity in a graduated system of surface adjustments. In the last year or so, I modified the table based on one provided on the MoRich site while adding some of what I've learned over the years. The table is attached to this topic as an portable document format (PDF) file. I submit this as a contribution to the collective knowledge of the forum. The table accounts for differences between ANSI/CAMI (U.S) and FEPA (European) abrasives grading and also includes scuff pads, and polishes, with and without abrasives. If you see anything that seems amiss, please feed back.
Special thanks to MegaMav, Mo and friends for their vision for the BowlingChat forum.
Thanks again,
Jim B.

Re: Bowling Ball Surface Adjustment Table
Jim, thank you for the contribution and your feedback.
We have something similar on the wiki:

Would you like me to upload your reference chart to the wiki as a companion to the grit conversion chart?
I'm curious to see what everyone else has to say about your chart.

Re: Bowling Ball Surface Adjustment Table
Hi Eric,
Thanks. Yes, I've seen the chart on the wiki and agree that it is an excellent, comprehensive reference.
I think the table I provided is also worth adding to the wiki as it provides, perhaps a simpler perspective towards making surface changes in logical steps.
