No sums. Adjust your flash exp dials to reflect its real output.

The elegant Contax RTS III does this. It has a built-in flash meter(!).
You can get readings from any unit that it will trigger.
But the "D" series Nikons and EX Canons work on the same principle
as doing manual flash, basing exposure on the GN & distance between
flash and subject. This works exceptionally well, eliminating the
guessamatic aspects of reflectance, though you're still stuck with
your film's ability to handle contrast.
