Tell us, can you get 75 fps, 100? 
Nope, but
74 FPS @ 1736x390 --> 1736x650 after 1.67 correction, of course on 700D

The Timer:(Slowed Down from 74 FPS to 23.976 FPS)
The settings are done in 720p60 , I turned off adtg_gui then adjusted the settings in photo mode, after that I turned on adtg_gui and went to video mode again, to avoid crashes when overriding the resolution

C0F06014 0x332
C0F0713C 0x1a8
I used mlv_rec instead of mlv_lite, the ML preview didn't work with mlv_lite when adtg_gui is loaded, memory error.
I noticed some hiccups in this preset, it might be fixable with C0F0713C, the LiveView is frozen but the camera didn't crash, I guess applying lower resolution and higher FPS at the same time will prevent the camera from crashing, the higher FPS is giving more data to LiveView to feed it to make up for the decreasing of data when lowering the resolution ?
I also managed to get working 78.607 FPS preset at 1728x186, I can get 80 FPS also at above settings but the camera is very slow at 80 FPS, can't start the recording, and if I applied 80 FPS in the working 78.607 FPS preset, as soon as the recording starts, the camera will crash.

Note: 6D has DIGIC 5+ processor and higher Memory, 700D has slower DIGIC 5 processor with less memory, this might be the cause that 6D Can handle up to 96 FPS easier than 700D.
Didn't play harder with more higher FPS, also didn't try to decrease Horizontal resolution, I am not planning to fine-tune or get a higher stable FPS preset, since the Camera is Very Slow and these higher FPS mods unusable.
It's just Proof of Concept.
Have fun on other cams
