Does it follow that the biggest, best formed seeds will most likely
yield the biggest and best formed pumpkins? Or is it the luck of the
draw? Thx!

Actually, most old time seed savers saved seeds from the best pumpkin.
That may be the biggest, the most perfectly formed, the most productive
vine or a combination of the three.
