As a refresher, this is my understanding of S+I tech. Is this all precisely correct?:
1) I believe that each nation normally gets a +1% chance ("ULTRA") of detecting each and every enemy unseen unit, for every level of S+I tech that nation has, regardless of enemy tech, capped at 5%. For example, if USSR, USA, UK all have level 1 S+I, then every unseen Axis unit has a 3% chance of being detected at the beginning of the turn, regardless of Axis S+I tech.
2) I believe it says setting the S+I Increment value for all majors to 0 will set the research bonus to +0% research per turn and I believe changing this number does NOT change the "ULTRA" unit detection chance or affect breakthrough chance in any way.
3) I believe S+I tech also gives the individual nation possessing that tech a certain increase in chance of breakthroughs, regardless of enemy S+I tech.
4)I believe that normally (increment set to 1) that a nation possessing S+I tech gets a bonus of +1% research speed for every level they are ahead of each and every one of the opposing nations in S+I tech. Moreover, I believe only fully mobilized nations count for the "highest-level" S+I tech for a faction.
So for example, if USA hasn't entered the war yet, and S+I tech is as follows:
[ Germany = 2, Japan = 2, Italy = 0, UK = 1, USA = 2, USSR = 0 ]
Then Germany and Japan get +1% research speed, and everyone else gets no bonus?
5) I vaguely remember S+I tech might impose a penalty (-1%) research speed if you're behind, but upon reviewing the manual, apparently this is not the case. Was this ever true in one of the SC games or is my mind playing tricks on me?
As an aside, I think it might be best to simply eliminate the +1% research effect of S+I tech, because it's difficult to understand completely and thus it's a bit of a barrier to entry, and moreover it tends to get researched by both sides quickly and thus become a non-factor in any case.
Thanks for reading my post (yes I had coffee!)
