I'm never "sure" of anything unless I've run the sims myself. Even then I'm not totally certain unless several others more knowledgeable than myself have duplicated the results, since properly setting up a sim can be quite challenging in itself.

I attribute it almost entirely to the 10-splitting indices. Ranking #4 and #5 on the I-18, these are powerful strategy variations.

It shows them based on penetration. In fact, it can be quite educational to plug in various levels of penetration and watch the numbers change.

Average numbers can be used, but they will be wildly inaccurate early or late in the shoe. Again, couple this with the fact that you will always have a minimum bet out when these indices come into play, and it becomes just, well, not worth the effort. :-)
