I wouldn't make too many assumptions about who can do what with whatever software. There is no evidence to support the claim.
RTG operators can 1) adjust number of decks and 2) set the payout on the pure slots; setting the payout on all the remaining "slots" - ie. table games I don't see as being remotely distict. Reels are spun / "cards" are dealt.
Any data posted publically is of great value insofar as anomalies may be brought to light. That they are not on any given session is not a disincentive to publish random data.
Cipher - clarification here: you can run any log files through your programme and get a stats breakdown? I'm not clear yet about the actual purpose of the programme (pure stats? "trends"?), but I'd be delighted to give you my Bodog results for analysis. There are many thousands of hands so it may be beyond your capacity, but I'd be a very worthwhile experiment.
