Perhaps the data generated by these people can help formulate a reasonable conjecture of what "most" means.

It is clear, from a mathematical point of view what 'most' means:
a set of density 1. Unfortunately, no amount of computation will
ever resolve this conjecture. On the other hand, I have suggested projects
for which computation CAN resolve the conjecture.
