Average draw rate: 38%
Average elo deviation to 5+3: +12

Average Elo deviation is 12 so the 1+1 Rating has to be increased by 12 to get a propper comparison
(Actually it has to be something with the square of the difference ... too long ago, I think the difference is marginal and this will do):

While no engine is in another ball park (interesting expression) the maximum additional difference is 54 Elo which is quite a high number!

I have to think about that!
