I think you are confused.
There are two written sources in thus thread that state tips should be 10%. An online Wiki and an extract from a Lonely Planet. Whether one should trust either is debatable - I expect that we would have to agree to disagree on this one.
The other 3 links you refer to (did you read them?) state that tipping is performed by rounding up - a practice that usually leads to a tip of much less than 10%. This is backed up by the experiences of others in this thread and I will add my name to this particular list.
