Classic peak: 5.41%

Thirteen times XT's peak — and still thirteen times short of the 75% threshold. Era bounds are the whole job.

5.41% peak month · May 2016

250 of 4,620 blocks. Full era-bounded Classic count: 2,176 blocks. A naive bit-28 query without era bounds returned 64,928 — wrong by ~30x.

Bit 28 means Classic in 2016 and mining entropy later. Without era bounds the instrument lies while looking reasonable.
