I'm not so sure spending an average 30 IPC's to get a tech (any tech) is such a good idea as a saving maneuver. But if you're talking about one or maybe two rolls in desperation, then it's a legitimate longshot that could be a boon in the long-term. But it may not be enough to save the USSR or Germany. If things are bad for either of them, they may be making <20 IPC a turn. Even if it only cost 10 IPC (and some luck) to get Indust Tech, that would leave with 5 inf on turn one, and 15 after two rounds. Not much more than than you could guarenteed
if you hadn't of spent on the tech. Worst case scenario, you get no tech (or super subs
) and now you're down 3 inf. Unfortunately, the worst case is the most likely case.
