My pumps run till empty if i let it happen.Interesting. However, I'll bet many now avoid charging to more than 78%, because the pumps come on at 100%.
Even fewer charge to much over 90% because of the time it takes, and the loss of regen.
Dye to the asymptotic behavior of the voltage/SoC curve, does not take much to bleed off a tenth of a volt.
My guess is if you charge to 90% or less, not a problem unless you start at the top of a big hill.
