I did a fair amount of red crits (about half if I had to guess) with an unzoomed Lanka plus a 3/5 Point Strike (+100%); if it was additive, red crits wouldn't be possible since that would merely result in the same 62.5% crit chance a fully ranked Point Strike would net.

The zoom bonuses seem to be denied: without Point Strike, neither the second one (+ 0.3) nor the last (+ 0.5) resulted in red crits but a few non-crits. Though, these tests were still some indication of it being a flat bonus.

Now, with a 1/5 Point Strike (+50%), I had a very small amount of red crits. If Point Strike only increased the base crit chance (0.25 * 1.5 = 0.375), red crits wouldn't be possible (0.375 + 0.5 = 0.875). Including the allegedly flat bonus in Point Strike's boost (0.75 * 1.5 = 1.125) would legitimate the rare occurrences of red crits. This would also explain the roughly 50% red crit chance in the first example (0.75 * 2 = 1.5) with a 3/5 Point Strike.

As for the Zenistar, it's certainly hard to test quantitatively; though, it showed the same results for me (flat), as there were a good bunch of crits happening but it's hard to tell if it were about half (or 55%) due to all those procs happening. I didn't try True Steel yet since I tested these before I found the Point Strike interaction but Organ Shatter is definitely viable in any case (2x base multiplier).

So, I wouldn't really call it bad or even the worst Augment in any way.
