Thanks for the advice everyone. I just got on during peak hours and went to idyll shire and banged out some mudras.

In ten tries, I landed between 2.45 and 2.5 seconds from the first mudra to the huton cast. I'm assuming this is a bit tight. There seems to be an odd delay between when the next mudra is ready and when the mudra animation starts. When I tried to ignore that delay and speed it up, I rabbited all over the place.

BLM it is, I guess.
