They are adaptive and basicaly learn how you use the throttle (they learn your rate of throttle change) and make changes to the shift points as a result.

Yep, just as Mark just said, not bad for a 12 year old design.

The key thing they do is PWM a number of the solenoids allowing better control over the shifts

So ... if it's adaptive, when I hitch or unhitch my caravan there there should be a difference in the gear change pattern until the car's geabox ECU realises there's a difference in driving technique ie more boot required when there's a 'van behind.
I'm n ot convinced.  :-/ :-/ :-/ ... but more than willing to be proved wrong.  :y  :y

No, no sudden difference.....it will slowly adapt depending on how you use the throttle

its more to match the kind of driver you are.  for instance, mine tends to change up higher up rev range, and change down a bit earlier.  if she uses car for weekend, it changes up early, and down late.

Which is my excuse, because after the slow miles she's nursed it, being the sane and sensible driver we all aspire to be, when I do get to use it it's playtime a requirement that the car (once suitable warm) gets a "excerise" towards the higher end of the range.

I'm sure I remember being told that I should test the multirams properly from time to time.
