And so? Didn't it come to your mind the Phils were more easily accessed than Indonesia from the US, that there were more US expats in the Phils than in Indo, that Phils were an easier country to travel for english only speakers, that there were more cultural bounds between US and Phils than Indonesia (does Clark air base ring a bell, haven't you noticed english is taught at school in the Phils while only few indos speak english?)?
Put that into a dutch board and Indonesia will come first. No surprize.
There's nothing about diving quality here. So pls compare what is comparable and don't try to find whimsical correlations.
