Two and a half quick questions about tech

[Zamensis]

1. Does research speed increases after the historical year? I'm wondering whether editing one tech from 1936 to, say, 1925 will make it faster to research on Jan 1st '36?

1bis. If so, when does the bonus kick in? Say the historical year is 1936. Does the bonus kick in on Jan 1st '36 or Jan 1st '37?

2. I noticed, somewhere between 1.08 and 1.12, Mech '41 has been changed so that it does not require Mot '41 anymore, but rather only Semi-mot Cav. Out of curiosity, why was this changed? I get it that it makes it easier to research and produce Mech divisions earlier (useful for GER especially I suppose), but I'm not sure what to think of it. Wouldn't any mech theory be tested with trucks in the first place?

Technically if you started researching say 1,200 days after the recommended date rather than 1,000 wouldn't that mean that for the 1st 200 days it would have the max bonus before that started to decline?

Huh? If you're researching something 1,000 days after the recommended date, you'd get the maximum bonus from start to finish.

As Germany, I want to research year-1941 divisions early enough that I can upgrade as many as possible for Barbarossa.

Tech rushing land units feels like a must for Germany, UK, France, USSR (especially) and Japan for the period 36-41 - and everyone else (including them) thereafter.
