Ablative Shield cast level (in General)

My minion Hypothesis has AS trained and RoS equipped. The train page shows this:
Ablative Shield 563,327/293,729 281,673/146,874

My reading of this is that AS should cast for 281,637 HP on each of my 4 minions. In the fight log, I see this (Observation is wearing an AoF):

Hypothesis cast Ablative Shield on Observation (240,407)
Hypothesis cast Ablative Shield on Hypothesis (203,736)
Hypothesis cast Ablative Shield on Experiment (203,736)
Hypothesis cast Ablative Shield on Conclusion (203,736)

I'm getting about 72.3% of what I should be, so my first guess is that it's the penalty for having 4 minions. Is it a known issue that this doesn't display in a clear manner? Or is there something else I'm missing?

"With 4 minions you get 4 * 36.25% Ablative Shield efficiency. Total is 145% effectiveness." -from the wiki

563k * 36.25% = ~203k HP (which makes sense)

So it would appear, then, that it is a graphical error. Unless effect is always supposed to be 50% of trained. But that wouldn't really make sense because it isn't the real effect experienced by the minions. In this instance, the effect should be 203,736 because of the 4 minions.

It is just how it is displayed. It would probably get hard to update based on how many minions one had, especially when taking account familiars. Well maybe not hard but just more work than anyone wants to put into something so small.

^ As others have said the effectiveness changes depending on the number of minions in your party.
