In fact, "tardy" blocks have *less* probability of containing the solution
key because many of the tardy blocks caused by computers crashing in the
middle of a block. This means that if they crashed while processing a
block, then a solution had not yet been found in that block (because if it
had, the block would have been stopped there and the solution-notification
written to the buff-out). And since we have not yet received any legitmate
solution notfications, well.. make your own conclusion.
Even if you assume that only a very small percentage of the "tardy" blocks
became lost because of a mid-block crash, that small percentage still makes
it more probable that a block that hadn't been distributed at all before
will contain the solution key.
