In reply to geebus:
I'm new-ish to fingerboarding (12 months), and boulder about your level. I do have 10 years of fairly regular climbing under my belt/fingers, albeit without training in a structured way. It would be fair to say I'm a total punter so don't know what I'm talking about; on the other hand I can probably relate to your level better than the heroes, and I've had a lot of finger problems in my time (mainly from bouldering).
So far I feel pretty safe on the fingerboard, it seems a LOT safer than when I'm trying V4 - V6 dynamic problems, as it's so controlled. I think a mature and slow approach to adding volume and difficulty will keep you out of trouble. I am wary, and I prefer to fingerboard alone as I don't think it's the time to be egged on by mates. Whenever I feel at all tired or low motivation or any finger pains I skip the fingerboard, which means I actually only get 1 or 2 sessions in a week (+ 3-4 climbing/bouldering).
I started off doing repeaters as on the Beastmaker site = ( 7s on / 3s off ) x 6 then rest 2 mins then next grip. This seems a fine way to go, and a good way to start. Why not try this twice a week for 6 weeks and see how you go?
For me the Beastmaker regime was too hard to use my full bodyweight for crimps even on good holds, and that meant I left them out: big mistake! I should have done them, with some assistance (obvious in hindsight). So if you find something harder, make sure you do it!! but with a toe on a chair, or one hand on a better hold/easier grip, or use a pulley or bungee to support some weight. All covered in the articles of course, but not the same as experiencing it.
I switched lately to max hangs as I wanted to focus on strength; for me that's 4-8 second hangs with 15-60s rest between them, repeated about 4-6 times for that grip. I picked up somewhere that if the hang is over 8s you should make it harder, and I now add 10kg for the 3 & 4 finger open-handed grips (seems ok though I was nervous about injuries with this). I stop as soon as the hang times are below my first hang time for 2 hangs in a row. Then I move onto the next grip.
I'd say I can definitely notice the difference in my climbing now, and in fact I noticed the difference within a month. I think this is largely due to recruitment improvement, and it will probably slow down. V5 feels like it will become a regular occurrence very soon, from feeling almost untouchable 6 months ago - I'm happy with that.
Warm up is very very important AFAIK. Never less than 30 minutes of bouldering for me. I've started doing a sub-maximal set of pullups on jugs and a couple of easy 10 second hangs on holds I find easy too. I think this is the single biggest problem with fingerboarding at home. If I was doing this I'd either do 15-20 minutes of running (light sweat) or circuits (press ups, burpees, bodyweight squats, core work like situps).
I'd say don't worry about pinches to start, focus on 4 fingers open, 3 fingers open, sloper, half crimp. Like weight-lifting, it seems if you concentrate on the big few and do quality work, then the other stuff just comes along a bit too - at least at the starter level.
Lastly, I'd echo what others have said: get Dave Mac's book "9/10 climbers" - it's worth every penny.
