A little experiment (TI-MD)

[maximo]

Probably TI + MD makes both skills stronger than if were separate.

That is how it has been explained before. Monster Defense increases your accuracy when you are behind. In this sense accuracy means hitting closer to the lines, which means steeper angles. It's also unknown exactly how the game calculates "being behind". It could be in the set score, game score, or just some other variable within the playing of a point (like being at the baseline).

It's when you are behind in a game:

Play more precise shots and make less errors
when you are trailing in the game.

I don't think monster defence matter too much... the topspin are really effective also if you are in advantage or 6-0 / 5-0 40-0 .
I tried with the pros and the TI or Bouchard seems not effective as Quah's , the TI of Borg seems good, but maybe a little worse than Quah's, but also the stats are a little lower
