This is precisely what happens to the unwary SR player. You get .5 conversion from improved synth plants well before the WE I succeeds, hence you are rewarded by going BACKWARDS. After you have seen this happen you will wait until after WE I to get the synth plant, but the mod designer could remedy the situation by actually coding the synth plant tech to require the WE I. If the intention is not to delay the synth plant until after WE I, then a seperate tech level of .25 could be added (and perhaps the IC req for WE I reduced by the appropriate amount). Anyone interested could, of course, recode this themselves. If you are playing your resource cards right as Germany however, I have yet to need the conversion rate before WE I is well over and done with.
