TLA 360 owners Ibve a question

Hello !

Does anybody know what is the guide number (I hope this is the correct english expression for the term "Leitzahl") of the TLA 360 in zoom reflector position "85 mm" ?
I know it is 36 in "35 mm" but I want to estimate the power of the flash in combination with a tele-lens. I would like to compare the TLA 360 with some Metz flashes.
Or, in other words: What's the maximum range for the flash, lets say at f-stop 4.0, ASA 100, position "85 mm" ?

Thank you in advance !

The guide number is 50 at "85mm" Range at yours settings is 1.6-12 m according to manual
