How long does Kaspa take to fully stabilize mining difficulty after a block-speed upgrade?

Kaspa is designed to reach a stable mining difficulty within approximately 4 to 44 minutes after a block-speed upgrade. During that ramp-up, Kaspa builds its new difficulty window one post-upgrade block at a time; the proposal sets the minimum acceptable window size at 60 to 661 blocks, which maps to that 4-to-44-minute range at the new block rate. While the window is still growing but not yet at minimum size, the difficulty stays fixed at the parent block's level — no recalculation happens mid-ramp. The range is intentionally wide to let Kaspa's developers balance how quickly the DAA responds against how much short-term instability is acceptable.
