Date: Sat Jul 6 18:00:09 2024 +0200 Timestamp: 1720281609 Simplify ttPv reduction formula This is a revert of 2046c92. This patch is based on the fact that the ttPv reduction has proven non-linear scaling (as documented in the code, along with testing guidelines); however, the original patch had (erroneously) not been tested at VLTC or longer.

This patch is based on consistent observations that decreasing depth more in IIR generally has a bad scaling behaviour (good at STC, bad at longer time controls).
