Guidelines may change once MTO and SO reopen, but before the suspension, MTO was total spend across linked boutiques (my SA could see my purchases in Europe, UK, USA - he could not see my department store VCA purchases in the USA even though those department store locations are now run by VCA and he could not see my Asia purchases, though it seems like others may have at least some purchases in Asia on the same viewable history). So for MTO, if nothing changes, purchased within the same region when all boutiques are owned and operated by VCA and most international purchased will could towards your spend.
For SO, it is very heavily weighted towards the boutique set as your home boutique. The total spend still is what is counted, but approval by Paris was weighted on loyalty to your boutique as one factor (can be outweighed by other factors).
It seems that SO criteria will be changing when SO open up again; for MTO I have not heard anything one way or the other.
