In a Metal Addicts interview Yeung commented on his reasons for leaving Morbid Angel:
“I’ve been waiting to break the news for a while about this. Now seems like the proper time to do so. As some of you know, there have been some lineup changes with Morbid Angel. Unfortunately, due to financial differences, I will not be continuing with them. It has been a great five years being involved with Morbid Angel. I’ve met a ton of great people all over the world, played some amazing shows, and have a ton of great memories as well as stories. I wish Trey (Azagthoth) and Morbid Angel all the best. As for myself, I’m always up for the next opportunity life throws my way.”[3]
In 2006, Yeung hit 872 bass drum hits in one minute at a World's Fastest Drummer competition, which earned him the Fastest Feet Title for that event, though not the world record, which clocked in at 1034 hits in one minute, held by Canadian drummer Mike Mallais.[4] By Yeung's standards, 872 hits in a minute is comparatively low, translating to one minute of 16th notes at 218 BPM, which is considerably slower than the speeds he has displayed in his group work, which he has been said[by whom?] to get to speeds of around just over 247 BPM. Yeung has stated in interviews that he could have played much faster if he had been using his own setup.[citation needed]
