Okay, bear with me. After the little talk I had with
@Ed Seith and
@Ojas Sapkota in the forum I was curious how long I need to warm up these days to get Creep and Master up to speed.
I did warm up about 30-40 minutes for this BUT I realized (as I barely played to backing tracks before) that I've been playing Creep way too fast. Now I got issues with the timing when playing to a track, that's why I mess up the downpicking with Creep quite a bit.
I think I tried to play Master too fast too (but failed) so when putting on the backing track to Master it was quite easy to play it up to speed.
I don't know the whole songs so I can't tell you how it feels like to play this speed for 5 min + so this might be the next thing to experiment on.
