Oh man, it's not that bad is it :-) but yeah I was trying to think of a way to explain this in text and it's hard... but the closest English equivalent I can think of is the diaeresis, like when you say "naïve"... except, imagine if instead of blending the 'a' and 'ï' together, you made as hard of a constant-ish boundary as you possibly could. I think that's a rough approximation?
