It is infact relatively simple to figure out.
If you check the current date of your F6 engine that will tell you if it is F6a
or F6b.

Assuming you upgraded to 6a when it was issued which was Jan 23 all games prior
to that date are with F6 old or light (same thing). All games after were with 6a
or 6b. which apparently are the same engine with additional tablebase support
with 6b.

As 6a and 6b seem relatively the same strength wise while 6a, 6b are far
superior to the 6.

You could also have done like I and others did which was rename the files with a
hex editor so that the pgn actually reads correctly without having to change it.

Your using the original F6 does an injustice to the totals as does using Deep
Junior on a superior processor when it naturally has played more games against
some programs than others.

That alone leaves me doubting all the ratings I see there.

Thanks.
Sarah.
