OK, virtually all my MH miles have posted (Only 86 miles of KUL-PEN left). Dates of travel v. date of posting below, if its of help to anyone.

PEK-KUL (19/12) (18/01)
KUL-PEN (19/12) (N/A)
PEN-KUL (23/12) (18/01)
KUL-BLR (23/12) (18/01)
BLR-KUL (03/01) (23/01)
KUL-PEK (03/01) (23/01)

So about 3-4 weeks to post, in my case. All travel was in Z-class, except KUL-PEN-KUL which was discount Y, if that helps.
