Nice picture, but it says nothing.
Here’s a similar screenshot of the Covert Jump Portal Generator.
Notice how there is no fuel cost at all on the module? That’s because the mass-modified jump cost isn’t shown in these modules.
I’m 100% sure that my black ops bridge takes fuel from my bay though, and so does the titan.
You’re rounding halfway a calculation… 
The equivalent mass number for a MAnticore taking a black ops bridge is 0.198 in the example shown on the EVE uni wiki, yet I am 100% sure this ship does take my fuel when you continue multiplying it with the range and isotope base cost.
I’m not complicating things, I’m asking for consistency when new modules are added.
That’s the opposite of complication. It’s simplifying things.
