I don't understand what you disagree with. Yes, there is a risk. That is not controversial. I indicated there is a risk in a post above your first reply to the question.

What's relevant is how much risk there is. Then the OP can decide based on his attitude towards risk.

In light of the argument I put forward above (and also in light of the history on Flightstats) I would guess the probability that SK1635 gets an apron position is 10% or less. And if it gets an apron position, there is still a good chance to make SK1636 as long as nothing goes wrong with the bus transfer (like, there being a huge line of buses at ASO/ASW, delaying the drop-off of the SK1635 busses). But normally, you should make SK1636 even when arriving on one of the bus gates in the root of A. This assumes user yauee is reasonably well on foot (as the departing bus gate may be as far as A69).
