What is the gain versus house edge that using the I18 gets a player?
For example, if you're flat betting a 2D, H17, DAS, NS game with a .40% house edge assuming basic strategy, what does using the I18 bring that down to?
Apologies if this is in the complete guide to index play, but all I'm seeing in my copy is the percentage of total available gain of various index plays, not what the total percentage gain is from index play as a whole.

First, yes, ignore aceside's hideous (even for him!) answer. It has zero relevance to your question.
You won't find the answer in our book, because, with no spread and simply playing BS, there is no SCORE, since the house has the edge. But, your question is a fair one and is easily answered by simulation. I used Norm's CVCX.
Assumptions were 60% penetration, three other players at the table. The BS edge (from BJA3) is 0.383. Using the Sweet 16 (no ten-splitting), the house edge reduces to 0.31%. I imagine that those splits could be worth a few hundredths more. Note that, alone at the table, the house edge reduces to only 0.34%, which is logical, as you don't get the benefit of seeing any of the cards of the two players to your right before you play your hand.
Finally, with 1.5/2 dealt, the house edge reduces to 0.27%.
