All the years that I lived and worked in Boston, that's what we did whenever restringing a piano without replacing the pinblock. The climate there and the prevalence of forced-air heating in New England homes beat those pinblocks up so badly that if you only went up one size, you would have loose tuning pins within a year or two of restringing (if not sooner). Now that I am living and working in Northern California, often the block is still perfectly fine when the strings are shot (as often happens in pianos that live close to the ocean or in the fog belt). Even going up one size can often result in overly tight tuning pins. So one size increase is the maximum I dare do here - and often enough restringing with the old pins (using a dummy pin for making coils) yields perfectly fine tuning pin torque. The point is that one should not blindly follow some set procedure, but assess the conditions and determine tuning pin size accordingly.
