for me, i really canot recall much..but wat i see here is the Spin got AF med & u dun hv, the rest is quite similar ah..
but the only thing i can think of that is maybe case by case ba, maybe for u, dr zou find it not necessary to take on AF..
then for Spin, she only accu for 3 times continuous then the rest of the wk she dun need..whereby the rest of us here, hv to do it every wk except AF report tht wk...
