Is it ITTF compliant if rubber glued this way ?

Yes

how about increasing the angle so that the whole index finger is against the rubber edge?

You are correct ! In Principle, you can't put anything on the rubbers under ITTF rules . I am testing this rubber so I  used a very diluted glue  for easy removal . The overlapped edge tape was intended to ensure further  attachment to the blade  during the testing period .

If the electrical tape does not show on the rubber surface , then we are O.K.  BTW, I usually replace the edge tape by  electrical tape and make sure it covers both the rubber & the sponge edges .

I wonder if you lose the point when you (accidentally) hit the ball by the naked wood - you probably should, otherwise you could play with half blade under rubber and half blade naked wood and try to use that to confuse the other player. In a regular situation you have small area of naked wood but you really cannot hit with them on purpose, that would be most likely same thing as hitting by the edge of the racket.

The ball has to hit the rubber not the wood. Just like in the case of cpen players who only use one side with a bare blade. When they hit the bare wood they will be penalized a point.

As for naked wood on one side of penhold blade - yes, this case is specifically prohibited by the rules. But generally there is no rule about hitting (accidentally, I guess) naked wood - you can hit the ball with the edge, handle some such tiny area of naked wood between lower edge of rubber and handle etc. However there must be some understanding of what is "reasonable" approach in this case.

For instance, we all know that the rules and the guidelines for umpires demand there would be no more than 1-2 mm of naked wood on that part of blade's face border from around 7.30 through around 4.30 (wall clock settings).

ITTF 2017 Handbook
2.4.4 The covering material shall extend up to but not beyond the limits of the
blade, except that the part nearest the handle and gripped by the fingers may
be left uncovered or covered with any material.

The rule doesn't say anything about any specific grip, just that it is legal to cut the rubber so your finger(s) nearest the handle rest on bare wood. In the case of a PH with gap, a person could have very large hands and have a large gap.
