Nice numbers, BUT...
...pretty much meaningless, IMHO.
Again, IMHO, the *only* number that matters is the ROI. This number, of course, is unaffected by the non-decision rolls in craps.
Non-decision rolls in craps are not, IMHO, the same as "push" in 21. I consider a push to be a *decision* of zero. The primary difference is that a non-decision roll in craps does not end the pass, but a "push" in 21 does end the round. Also, non-decision rolls in craps do not measurably wear out the spots on the dice, but pushes in 21 do consume cards, sometimes to the player's advantage, sometimes to his disadvantage. In short, pushes (i.e., the cards consumed by them) can and do have an effect on the game, non-decision rolls in craps cannot and do not. Just MHO.
For the fellow who doesn't want to or isn't able to count, my advice would be to go to the lowest minimum bet tables he can find, and either play the Ponzi system for craps or use a betting progression in 21, and hope for some pure luck.
In the short term (which is the context here set forth in his query), anything can happen; so long-term average loss rates are not, IMHO, really the best criteria upon which to base the decision.
In the short term, even with only moderate "luck," he has a much better chance of getting a decent win pressing bets (in both craps and 21, but especially in 21) than playing craps the extremely conservative way you suggested.
In the long term, all these methods are losers, but given the fact we're talking exclusively about the short term, I would suggest he set definite loss limits and win goals, and use a moderately agressive betting progression at the low-limit 21 tables.
