I would even say that the OP's document overestimates the TiChrome's ability to fight multiple enemies. Unless those are particularly weak enemies like locusts or burrower spaw, i always preferred to use either tungsten or preferably Balor regardless of wherever i am light or heavy armor.
As it has been metioned, 10 AP leftover for regular hammers is very useful for various purposes, like using medicine or moving, but what is most important, 10 can be used to recharge your hammer. All the calculation of comparative damage seem to assume that you can just attack continuously, but that is not true. With electroshock and core being of relatively similar quality, it take around 4-6 swing to deplete your hammer's battery, which means that TiChrome hammer had to be reacharged on average every 2 turns, so in reality we are not talking about 3 attacks per turn, but more like 5 attacks per 2 turns if we are keeping up electroshock. For regular hammers this is not as problematic, since you can just recharge with those leftover 10 AP. If we also account for Pummel that costs 10 AP too, then it's even less favorable comparison for TiChrome. around 15 attacks over 6 turns for TiChrome vs 12 attacks + 2 pummels (they give half of base mechanical damage but full electrical damage, so i don't know proper rate of conversion between pummel and regular attack) over 6 turns for Tungsten. And yes, you can lower the AP cost of Pummel, but that has an opportunity cost that regular 20 AP hammer does not have.
I have playes a lot of hammerers and in the end i mostly prefer 20 AP ones especially Balor.
