Cloaking question

[dumbluck]

Level 0 scanning is present in the game. All ships start out with level 0 scanning in all types except EM-Active. So there are benefits of level 1 scanners (accept in EM-Active, which by default starts at lev 1). Now if you skip from, say, temporal scanning 0 to temporal 2 (as you suggest), what's the point of having temporal level 1 cloaking? You would have to research 2 steps of temporal cloaking (0-1, then 1-2) to beat the one research step of temporal scanning (0-2). THAT doesn't make sense....

Granted, in the early sensor/cloak rush, anything besides EM-Active would be a waste. But once you got up to EM-Active 4 or so, it would be cheaper and quicker to research a different type of cloaking instead of the next step of EM-Active. And unless your opponent can successfully guess which type you switched to, you have a window of opportunity whilst your opponent waits for the research to complete on the next, now rather expensive, level of EM-Active.
