I suspect it's an individual thing and you're probably best chatting with your CDC about it.. I've done each plan weekly myself.. so each week I chat with my CDC about what's right for that week.. I've never jumped from SS to 810.. this is the order (but each one's been several weeks):
started on 810 (preparation)
then SS+ (preparation)
then SS (the real thang)
then SS+ (prefered being on SS+)
then 810 (for health reasons - had to)
then return to SS+ (once I could)
then 810.. (in prep for month's hols in asia)
now back to SS+ (hopefully til I get to BMI 25
)
then plan to go up at least a couple of weeks on each, if my weight will allow me to.. the longer I'm on each the better, so long as I don't loose too much weight on each
so.. that's my plan.. but we're all different, and we have different health/body/emotional needs.. so this has been very specific to me, and done with conversation with my CDC..
Hope that helps a little..

This sounds all over the place, but it's been carefully planned, and each one has been for many weeks and for good reasons.. always talked through with my CDC..
