Mace is also pre-prime in his fight with Bulq (he muses in a book closer to RotS how he's developed Vaapad since his fight with Billaba) and it's only logical he would have increased throughout the war, by being in combat so much.

How does that make him more technically skilled? I think that his better understanding of the his own darkness and the Darkside as a whole is what allowed him to create the superconducting loop against Sidious via Vaapad along with his own heightened emotional state. I don't think it made him more technically skilled.
