But they aren't minor! If we take Colin's word in the video I linked, 20 - 40% of our edge comes from playing deviations, not betting variation. But, a lion's share of the value from play deviations comes from Insurance and 16v10. So my question is how fast does the value of deviations drop off (for example, https://blackjackincolor.com/truecount3.htm here you can see in the first chart that the I18 get you most of the value of full indexes bet -3 and +6), and which are next on the list?

And, as a corollary, what indexes are valuable under different systems than those the I18 were made for? (3/4deck, s17, 1-12 bet spread)
