In fact sometimes the first profile I make when entering profiling mode sucks and I have to start from scratch as no amount of refining seems to fix it, I'm not sure why (it could be a bug, or perhaps some bg noise got in during the initial profiling test signals pass).
One tip that I've found invaluable is to use SPDIF and set up a dry guitar track to re-amp (and re-record) during profiling. It's the only clear way to match them against each other without hearing more from the amp during playback than you want. I've suggested that Christoph add a re-amp loop during profiling in order to hear the sound side by side so you don't have to do this and he seemed to like the idea on the forum, but it's yet to make an appearance.
