Ah, I see you simply don’t understand how this works. One block a day means miners signaling for BIP110 have a reasonable chance of receiving payouts within a single difficulty epoch. They only need to keep mining for two weeks until the next difficulty adjustment kicks in. Even if we assume no additional hash rate joins BIP110, once we reach the activation block height, every BIP110 block remains valid on the legacy chain, while legacy blocks are no longer valid on the BIP110 chain. That creates a temporary chain split, but it poses no risk to BIP110 miners - they simply continue mining their own chain for the next 2,016 blocks. At the following difficulty adjustment, the BIP110 chain’s difficulty drops by roughly 99.2%, bringing block production back to the target of one block every 10 minutes in average. At that point, the remaining 99% of the hash rate suddenly has a massive incentive to switch over. They have everything to gain by mining the BIP110 chain and even more to lose by staying on the legacy chain. Why is Mechanic correct and other pools won’t wait so long to react? Because they understand exactly how these incentives work. No miner in their right mind is going to risk forfeiting an entire epoch’s worth of block rewards by refusing to switch once the economic reality becomes obvious. I think it’s already obvious, but let’s wait another month until it sinks in.
