Obviously I know the 80-100k is the average and my understanding is you always referenced that in EV and that's how I used it. It doesnt matter EV or actual(actual being even more unrealistic), my argument was and is the same. It seems unrealistic to do that all in vegas for 16 years.
My whole career has mostly always been either a purely focused backcounting only approach with a 1-4 or 1-5 spread or a very aggressive white rabbit wong out at -1 approach spreading 1xmin to 2x150, 2x200, 2x250, or 2x300. So to answer your question, i did use a big spread and played very little negatives. The good thing is they didnt see a lot of my waiting bets before finding a new table. Combine that with short sessions and a lot of times they didnt really see a big spread at least not in vegas.
There's also a very little understood metric called departure adjustment that few people understand what it means or the effect on the win rate and n0, and no, departure adjustment isn't just wonging out. This is really norm's fault because no one has any idea what these wonging out sims are telling them. It's in essense white rabbit as Don described in his book and he kind of went into it a little bit with 6 round lag times before finding a new shoe, etc, but he used static numbers such as rounds per hour and limited spreads. Thr confusion lies in how to actually calculate the effect off this. If someone sims a wonging out sim on CVCX and doesnt check the 'departure adjustment' box, youre basically telling the sim youre wonging out BUT sitting at the same table until the count recovers. What departure adjustment does is it tries to estimate the effect of not only wonging out but finding a different table and gives you a ticker to click how many rounds it wouldve taken you to find a new table. Obviously, the less rounds, not only does the win rate skyrocket, but the n0 gets slashed because youre not waiting for the count to recover at the SAME table. Because people dont understand this metric, but nonetheless adopt this playing style, they never know if theyre running worse or better than they think when they look back at their results.
So yes, ive always used a pretty blatant heads up spread, but the first 2 years or so in vegas i was mostly backcounting, which coincidentally looking back resulted in almost no backoffs or trespasses, but I was also playing a lot less, much smaller stakes, and I was also new to town so could be biased. I also mostly backcounted in PA when building my bankroll. If i go back to blackjack, im going to probably implement the higher bet at 0, which you do, as that has a very low impact on n0 and EV and results in a much smaller spread and therefore longevity. Probably will incorporate a 2 hand approach the whole time as well instead of the prototypical 1 to 2 hand counter tell
