It is now rider armor * 0.67 + mount armor, which is already slightly under the equivalent rider armor. I am pleased with these new values so far and with armor upgrades the values can still be pretty high. Note that mount mass values have approximately doubled since the previous version - this does not lead to much of an increase in target casualties but makes cavalry charge effects much more realistic. The entire raft of new cavalry mechanisms and infantry defenses against them synergize quite effectively, we will see how the player reaction is to them.
You can see all this in the RRRC_Ultimate.txt guide.
