Well, at first, regen function was wrong coded as it shouldn't return anything and it must set the regen value

Argn2 in @Gain is a % of gaining a point of skill and <r100> gives you a random numer from 0 to 100 (you can use it also like <r1,100>, <r5,15> or any number(s) you want), at low skill rates argn2 is 90+ so you'll have a VERY HIGH chance of skillgain (you may want to test it further and make a better calcs or wait if someone have a better way of doing it!) as if (<r100> would almost always be lower than this <argn2> until this skill goes up)

50 in this whole code is focus skill number, so skillgain 50 means skillgain focus and 50++ does the same as 50=<50>+1 (i'm using 50 as key for focus but you can use focus ++ wich would result in focus=<focus>+1). I don't know if you were asking about '50' or the '++' but I tell you that you can use ++,-- for add or sustract values for an existing key (tags,locals,stats,skills, almost everything that it calls itself in same way to get values and to set values)

And you got what this does perfectly. But i will clarify your point 3: As you said, skill GAIN check is performed on focus, if it passes it got increased AND ALSO your regens updated, otherwise won't gain nor call for regens update, and it will return 1 the default gain, so we don't have double gain AND in this case not-updated regens
