Advanced Dungeons and Dragons, old school 1st Edition style. I only ever played 2nd edition very very briefly. Also you can get OSRIC here http://www.knights-n-knaves.com/osric/ for those like me that don’t have the original books anymore.
They begin at +1. See the end of this section for the ladder. For each, roll 8dF. That is 4dF twice, added together. Add the result to +1 to get your skill rank.

Having reread Super Squadron again recently, one interesting part near the end of that game involves the conversion of existing experienced heroes to the system, which does have an experience level statistic.
The ballparks used are comics the hero is currently starring in. If you are comic geeky enough you could certainly do that, or find out all the series that people are in. It gave fractional experience level awards if part of a team…e.g. X-Men, etc.
If you like more granular standard four-colour superheroics with respect to established heroes and your newbie Fate characters this an idea that I have been considering.
A simple way to look at it for Fate and its standard Milestone experience system would be to award a Major Milestone for each year of existence of the character. Perhaps lowered if only part of a team in a comic sense, as per Super Squadron. Divide by two or by four or something along those lines.
So, for example :
Superman
Starting Character, Fate Core
High Concept: Last Son of Krypton
Trouble: Kryptonite does bad things, whatever the colour
Aspect 1: Secret Identity, mild-mannered reporter Clark Kent
Aspect 2: Just a smalltown farmboy at heart
Aspect 3: Truth, Justice and the American Way
Super Leaping
Super Strength
Super Speed
Invulnerability
