I take it you must be talking about Synergism users. I have no idea how Purdy adjusted the Beyer ratings, though there is a long discussion in
Beyer On Speed on extracting the variant from a Beyer figure. At that point, you would have a variant on the Beyer scale, and would have to convert it to DRF terms. That's not all that hard to do, but in Beyer numbers you have vauiable points at different distances instead of the old DRF/TPR fifth of a second per point. Its not all that difficult. but requires either a computer program or a bunch of charts and fast fingers on a pocket calculator.
I also have no idea where Purdy built in the variant break in Synergism. Is no variant adjustment a 0 or a 17? If you are talking about using the numbers raw, with no variant, you simply have numbers that are listed in the book, without the adjustments for variants. I always found the raw numbers to work very well, within the obvious limits, just like the matchup.
