Of course time helps. I guess the difference between 8 hours time and 
1 hour time gives an advantage of about 13 points (1 amateur grade) at 
the top professional level, which will probably swing the winning 
percentage from 50% to 90% at that level. Is this about 200 ELO? I 
would also benefit from more time. However, i don't think that 8 
folding the time limit once more will bring the same 200 ELO increase 
in winning probability. The human mind does not scale like this, i 
think. Also you have to train to use this much time effectively, to 
stretch you attention span as much as possible.

In Europe time limits in tournaments are usually set to about 1.5 
hours. Increasing it to 4 hours will surely improve my winning 
probability, because i can avoid a lot of (mostly tactical) mistakes. 
My guess is i may gain about 20 points (i guess that corresponds to 
150 ELO at my level). But giving me 8 hours will not improve it very 
much more. I don't think any time limit will increase my level by more 
than 200 ELO (30 points?), because:
1- I would not have the stamina to use this extra time effectively.
2- Mark Boon pointed out the problem of conceptual barriers. I just 
lack some of the concepts that 7d players master and I can't master 
these concepts on my own by thinking very hard during the course of a 
game.
