a while ago I posted this question about my ideas for guitar practise: Guitar practice - general techniques
Since then I've been using the little app I put together, ranked up about 40 hours or so in total and it's been mostly great. I can record how much I've been practising, it slows me down when I make mistakes, gradually speeds up, etc.
I found some interesting things which made me tweak how it works along the way.
But mostly - I seem to get 'stuck' around a particular BPM, about 75% of the target BPM I wrote the riff/part for, for the past couple of weeks. That's across 3 or 4 different sections, which I practise on average between 10 and 20 minutes each every day (i.e. total 1 to 2 hours each evening, ish)
Usually I pick up each riff for the day, make some mistakes and so drop down 5 or 10 bpm or so until I play it consistently. Then, the BPM rises to about the same place (or slightly higher, slightly lower) and the time for that exercise/riff/part is finished, so I move on.
I sometimes make better progress on the days I can do 20 minutes on each part, but there's rarely a good solid leap.
The good part is my app can throw out a graph of date vs BPM, and it's recorded everything I've done. The frustrating part is the line goes up from my starting tempo (30 or 40%) to about 170 bpm in each case - despite some being 16ths, some 16th triplets, some sweeping etc - and has stayed there for a couple of weeks.
I have no doubt it's doing some benefit - I can relax more, play for longer, and when I 'mess around' and try the thing at a high tempo (or full tempo), it sounds a lot better than before - albeit it lots of mistakes.
I want to see what everyone makes of this: am I reaching some talent-based limit, technique-based limit etc? I feel as is everything is relaxed and when watching myself in the reflection of my old monitor, there's no stray finger flailing around, no massive inefficient movements etc...
(Oh, as per my original question's best answer: I do warm up with some chromatic runs.. despite it sounding like a terrible affliction.. for about 3 min, which seems to get my fingers / muscles in the mood)
Can anyone comment or provide any tips, thoughts?
