Delta 400 and Tetenal Ultrafin liquid?

I cannot find dev data for this developer - it came without instruction.
From what I found in the internet, only jobousadarkroom instructions for Jobo rotary processors... they are not suitable for small(inversion) tanks I think.

If somebody have such experience with Ultrafin liquid, please share your dev data.

At the back of my botle of TT Utrafin Liquid it say's:
Dilution 1+10 10 min. with inversion rhythm at 1 min.
Dilution 1+20 9 min. with inversion rhythm at 3 sec
