Levi's Double Dice

Just a quickie - On the new G+ Gamecraft community (and communities are brand new) Levi Kornelsen asks the following:

Okay, so, dice mechanic thing; kind of a "little idea" I keep playing with.Consider a character with skills like those in Skyrim - so, ranging generally from 15 - 30 to start, and up to near 100.Now, imagine you roll 2d10, and read them as percentile both ways.  So, 9,2 is 29 AND 92.If you succeed (roll skill or less) one way of reading?  Partial success.  If you do it both ways?  Complete success.How does that hit you, overall?  Gimmicky or good?    #rpg    #roleplaying   #rpggames  

And here is what the cumulative distribution if Partial and Complete success looks like, assuming you need to roll your skill level or less, and "00" is both "0" and "100":

That's it --- I said it was a quickie!
Edit: Maybe the chart title should be "2D10 Double-Dice". Oh well ...
