real slog developed at a fixed point

Not to the values of slog. The radius of convergence of the sub-series of terms with integer poers of seems to be .

Oh I just see, the construction I made above is the regular slog. I.e. the function Knesers starts with. Thatswhy it doesnt yield the values of the kslog, especially it is not real at the real axis. It is the powerseries development of the regular Abel function, while Kneser works with the limit formula of the regular Abel/Schroeder function.
So the continuation of this series to the upper half plane has a singularity at for each . Here the singularity at 0 limits the convergence radius to .

Lets call this super logarithm rslog while we call your super logarithm kslog. Then we know already that


where is 1-periodic.
By the above consideration we can develop
for a powerseries .
And every 1-periodic holomorphic function can be developed as:


Now the exponential of a powerseries is again a powerseries:


thatswhy we can finally write:

which is slightly more unspecific than Knesers's formula.

Did you forget a binomial coefficient somewhere? More specifically:

Yes, you are right. I will correct it in my post. However I think the coefficients are still ok (because I computed them by other means.)
