No it does not.
OBT is not a powder node (OCW). And it's not an accuracy node (as obtained from a ladder). And QuickLoad does not predict anything about tune.
OBT is really a misnomer for 'Bad Barrel Times' (BBT). That is: stay away from these timings, else the bullet could exit at an exact point corresponding with bore/crown expansion. It's hard to buy into that,,, as it would be really really hard to time a bullet exit so exactly, and actual measure would be difficult and expensive.
I've had & used QuickLoad from about 5minutes after it first hit the streets in the USA. Maybe ~25yrs or so.
I don't like or care about OCW, because I want the most accurate loads over most forgiving loads.
Ladders provide indication of most accurate areas to work with. It's basic incremental load development from there.
