Is depending from the area
Mine get full upload when fully got updated (100/10) and so mate next door from 10/1 mb got 30/3 straight away
Then the extra 2mb upload will be much later when the 120 will completed
But some areas looking in this thread, it did when the 120mb finished

But remember even your area has fully updated then upload in some cases follows little later and some times before the fully 120
From your question i am guessing you got 100/5 but not the 12mb...
If this is the case when your area was fully done? (not the extra 120 but the normal updates)
