of course your wrong doing that voodoo and you know it! lol.
that said i'm in total agreement and do it
sometimes and other variations of that theme as well. lmao.
IMHO it's a more complicated issue than the ' game of blackjack is just one big long game' view point. i think it's only one big long game if you play the same way every time for a long time. so but what your doing will slow you down getting to N0 but you know that. and if your playing at an advantage there's no reason to ever quit or to not bet according to Hoyle, but then you know that as well. but you also know that you could get ruined doing so.
it can have implications for your ROR as well. the question of how is hard to say because there is probably the question of how consistently are you going to vary from Hoyle in the long run. just as over betting can raise your ROR under betting can do so as well. you could however protect your self in that sense by watching your bottom line and results and holding those results up against the yardstick of what a perfect player should realize for the same number of rounds played. and then going back to proper orthodox betting accordingly if your off that mark.
then there is the psychological benifit arguement for doing what your suggesting and the benifit to your hippocampus.

so those are just things you want to take into consideration as far as do you want to do that voodoo.
one thing i think about is the issue of the question of is the ' game of blackjack is just one big long game' view point. to me it's not, i should think that for a professional it probably is. me i don't play enough or play consistently enough for it to likely ever be one big long game. but one thing i do know is for some game what a perfect player could expect to make if he was playing one big long game. if i do any where near that 'ideal' dude i'm happy and will quit or lower a bet in a heart beat to like you say lock that money in. i could care less about being greedy but i want that money and i want it now not in some fuzzy date in the future lmao. but i'll take it in the future if need be lmao.
thing is when you do something to lock that money in you don't know maybe you guessed it right and you just avoided some negative fluctuation or maybe not and you just didn't win a bunch more loot. so to me it's just a matter of deciding on the spot which is more important to you. so but this fluctuation stuff is another consideration. one of four things could happen with it (maybe more), you could win a whole lot, you could win a 'decent' amount, you could lose a little or your could lose a whole lot (maybe enough to ruin your bankroll). me i prefer to win a 'decent' amount or lose a little for any given session. i'm an imperfect player even when i try to do it right. if i was a perfect player who could do so painlessly maybe i'd see it differently. and yeah if you do this over and over there is the idea that everything should smooth out and you'll eventually hit some big losing session or sessions or have a bunch of little losing sessions to smooth it out sort of thing. maybe that's right but i'm not sure it's written in stone. maybe if your as inconsistent as i am or maybe if you switch up what you do then perhaps it's harder for that smoothing process to happen. maybe it'll happen to some body else instead of you lol. so if it's all just one big game after all. then maybe this question could come into play.

point being are there things that can happen that maybe a simulation wouldn't expect? or if you don't play that much isn't it true that 'in the short run anything can happen'? if that's the case might it be possible for your judgement and thoughtful actions to help that anything along?
maybe those questions can become considerations if your blackjack play is no big deal and nothing life changing sort of thing instead of being a professional.
so a bunch of speculation on my part. thing is did you notice in that one link that went to QFIT's blackjack book page about having quiting points (and i would think it could relate to underbetting as well) that says "Obviously, if you play out the shoe or wait for the count to drop back before ending the session, you won't see any decrease."

the point being what your doing may slow you down reaching your long term expectation but you could still get there. the biggest worry would be that you increase your ROR by underbetting. if your gonna do that voodoo stuff you should definately play against a yard stick and guard that bottom line so as to not wade into a ROR over your head.
