Rorqual Bridge module => wrong megacyte number?

after finding the number quite huge , i decided to check the other modules, and here what shocked me :

am i the only one who think it should be 15k megacyte and not 150k ?

Compared to the (titan) jump portal generator it seems the industrial jump portal generator sometimes takes less, but sometimes takes more minerals.

For many minerals it takes less than the (titan) jump portal generator, but for some it doesn’t.

It takes 4 times as much Pyerite for example, or slightly more Isogen. It’s not that strange it takes about 50% more megacyte as well.
