Something I've noticed with both my flash guns (Godox TT350F & TT685F).
When in TTL, the flash is able to be brighter than when using manual settings.
Scenario.
I will quite often use this trick when manual does give enough light, but... I would rather be able to get this extra light in manual as TTL can be tricked (reflective surfaces etc.)
I've noticed that the High Speed Sync icon is showing on the flash gun, but I'm staying below the sync speed (and I thought HSS reduced power).
Any idea what's happening / what I've got set up strangely / and what I could change to enable this "extra" exposure in manual?

Scenario.
- Indoors or outdoors doesn't matter
- ISO set manually (generally 100)
- Aperture set manually
- Shutter Speed set manually - normally the max sync speed of 1/250th (but also observed at 1/125th to).
- In Camera flash settings left as defaults.
- Observed on both the X-T2 & X-T3
- Flash on camera, pointed Up (not forward) into an fstoppers flash disc to diffuse the flash (I'm running and gunning at conventions, rather than in a studio set-up, having a softbox on a stand is not normally an option (think 50k+ stuffed into the half of the ground floor at the Excel)).
- Flash set to 1/1 power (max on the Godoxs) and depending on the distance from of the flash from the subject it may be underexposed.
- If it is underexposed, keep the distance the same and swap to TTL, where you can go +3 from "correct" exposure, the image can often be exposed brighter (distance is still important, but...)
