Depending on how the advantage is gained, counting, shuffle tracking, etc the variance changes and therefore the Element of Risk changes and a good player would relate that to his/her bets.
Also, Kelly betting should have a practical relation to the BR not only a theortical one. Someone with a $1mil BR would not be able to get away with a full kelly bet in almost all venues due to table max, even if they could stomach the risk.
But this is an interesting poll nonetheless. I am a proponent of the half-Kelly approach while counting using Zen on 6 or 8 deck games. And my vote in the poll may reflect that!!
