I don't think that force carbing is the same "AKA" as the shake method or high pressure with purging. I've heard those called burst carbing. Setting at 30 PSI for 24 hours before dropping to serving and not purging is kind of a hybrid. It's not true set-and-forget force carbing, but speeds up the process without the negitives and risk of over carbing.
Simply burping your properly carbed keg to get the pressure down for bottling is not the same as charging to 30psi, shaking and then purging like some people do when burst carbing.
Hmmm however, the topic of losing hop flavor still intrigues me. Thanks for giving me something to research!
