I don't know why a +1 isn't 'enough' it is a small increase that goes up fast... but starting at +2 like 4e did would be fine by me tooStarting at +1 is a bad Idea, because it is not significant enough. But I think that would have been the right direction.
I'd start at +3 and then add 6 or even 7 over the levels.
all of the 'where to start where to end' is actually not important. You can start at +1,001, and end at +1,016 or start at +0 and end at +15 and it is the same thing
