As a newcomer to the sheets, I would love to hear a little about the start of the whole sheets evolution and the comparison between Ragozin and TGJB.  Was Ragozin first, etc.?

TGJB: The first thing you should do is go to the Archives section of this site and read \"History Lesson\", which is about Donaldson, who preceded both of us by many years.

In the Archives you can also find \"Changing Track Speeds\", which is about the main difference in methodology between TG and Ragozin.

Best place to hear a little about the history of yours truly and Len is my opening remarks at the DRF Expo of 2004, or by doing a search on this site.

drbillym: Thanks.  Tried to get through \"Changing Track Speeds,\" but zzzzzzzzzzzzzzz:)

TGJB: Quite a number of people at the DRF Expo agreed with you. But it is important stuff, and discusses the primary difference between us and Ragozin.
