Maximum 10 hours, but I'm usually drained afterward. That's only if I'm in the middle of a big push, like for an MVP or something. Average is probably 6 hours, assuming the requirements are well defined and I know the language and system well.
For poorly defined requirements, a language I don't know, or any other "bullshit" variables, tack off two hours per bullshit variable. Hence if there are 3 or more bullshit variables, my productivity effectively goes to 0. (A bit tongue in cheek of course; really one should take responsibility for one's productivity no matter how much bullshit.)
