And it's a pool that handles ~ 1% of the total SIGT hashrate. Show me another pool that has that many orphans. You can't because there isn't one.

Besides, my understanding (which may be wrong) is that forks occur when pools are running different versions of the software & with different ledgers. Since these are orphaned blocks,  can there really be a fork?

EDIT: My bad, that was from chainworkindustries.
