So, granted that they didn't do a PCC, what minimum time after

should they have waited before launching in order to be safe?

Actually, on the field where I usually fly, in a situation
like this where a glider has just been assembled, either
the tow pilot or the guy running the line would ask the
PIC if the PCC had been completed. He could go ahead
and lie if he felt like it. OTOH he could have waited. All
afternoon.
