Thanks Johnson and Hampus for the clarifications. However, I would rather do the opposite: soft-fork to 50% now, and soft-fork again to 75% discount later if needed, because it doesn't affect the max transactions/second.
Segwit as it is today should be activated. However if it is not before November, then for the next Segwit attempt I would choose a more conservative 50% discount.
