I've read varying opinions on how much flash power you have in auto-fp flash mode at high shutter speeds .
This weekend I will devise a test to see what results I get .
The distance info reported on the flash head suggest you have a little over 25% of the power of normal flash [ 2 stops less ] but many are reporting 2.3 to 2.6 stops less power .
