How to make Tech come out sooner?

[berte]

In the ResearchAreas2 file, under [Missile technology 19] there's this:

Reliable SSM;1955;N;70;12;1902;Increases SSM hit rate

1st of all, what do all the numbers and letters mean?

2nd, if I change the 1955 to say, 1954, will that make that tech available 1 year sooner? 

Thank you!

From bcoopactual here:

Take the Research Areas 2 file in the Data folder and each tech has an entry like this:


Supercharged diesels;1943;N;70;10;25;Reduces weight of diesel engines by 10%

1943 is the nominal date of discovery. if you are researching the tech before you get to that game year your RP rate in that one area is throttled until the year is reached or the tech is completed anyway.
N means that the tech is not more likely to spread once it is researched by the first nation that completes it. If it had a Y then the chance for other nations to research it goes up once one nation "discovers" it.
70 is the percent chance you will research that tech when it is checked. 100 means that tech is always researched when the previous tech is completed. It will never be skipped. It's not a go/no-go check. Usually if there is time left in the game you will go back and research a previous tech that was skipped the first time so the game does usually re-perform the check multiple times a game.
10 is the multiple of "X" for the number of research points needed to complete the research. It was "X" = 20,000 RP in RTW1 but I haven't verified it's the same multiple in RTW2.
25 in this case is the Tech ID number used to assign bonus techs to various nations in the BNat file.
