Ive done some calulations for DAAKs low luck rules for this tech to Germany…
My basic idea was to research the tech fairly quick, but more dice gets expensive with the DAAK Rules so Ive puzzled a bit with buying two dice per turn which will be an avarage cost while you get the tech fairly quick. This will cost 33 IPC over the course of the first three turns and then the tech will come in with a 100% chance in GER#3 and you can start using them by GER#4
Now you can take 3-4 IPC away from both moscow and London and 2-4 away from caucasus (the damage is based on DAAKs rules regarding SBR damage compared to IPC value of countries)
This is an average damage of 10 IPC per turn (3,5 + 3,5 + 3)… Profit for germany on turn 8, but at the cost of 11 infantry who could be used to on the eastern front to trade territorries with the russians. Im affraid that putting this kind of money in this tech would also mean that it will take much longer to conquer Caucasuses.
I don’t think its worht it.
