First of all, no one would build anything but the hightest lvl component anyway . And remember to put a repair bay on it.

But, more likely what you are concerned about is building, say lvl 1 (100 sectors) when you don't know if it will reach and if it doesn't, then wait till you have researched lvl 2 before you build. Upgrading them is expensive. So, until then, you are left with SJ's formula (a squared plus b squared = c squared). (sorry)
