Limiter in what effect slot in the stereo out

Hi maybe a silly question but I have a limiter on the stereo out (main out) of my last track, it is on effect slot 5.
Effect slots 7 and 8 are post fader, now my question is this:
The limiter has a built in option for dithering, say i dither to 16 bits, will this then be useless because the original signal STILL goes through the main fader and the project is set at 32 float point, so should I place the limiter with dither on effect slot 7 or 8 or doesn’t that make much of a difference.

Thanks in advance.


Ah yes already thought so, thanks for the reply.
