Well if you knew anything about the subject matter you'd realise you can't consider one without the other.
If that's a roundabout way of saying that whether you're a Heavy or a Medium will affect your ROT, then I'd have thought that was so obvious as to not need stating.
On the other hand if you're suggesting that what happens between crossing the threshold and vacating the runway (the start and end of AROT measurement) is somehow dependent on the wake category of the preceding or following landing aircraft, I'd be fascinated to know how that works.
