I want to ask 4 questions about the BKR formula and philosophy of it and 1 more....:

Today i won an Atomic Chess game against an opponent who is 1782 BKR points, while i have 2438. And i won the amazing number of 0 points.....

My first question is:
How many points i would lose AND how many points my opponent would win if:
a)The game would be draw......?
b)I would lose the game.......?
(Better of course would be if Fencer would give the exact formula (not the known link which isn't clear) but i know Fencer will not(This is an observation-Fencer always avoids to give the formula....))

My second question is:
OK, the BKR difference between me and my opponent was big as the formula gives 0 points for a win (actually gives me a decrease of my BKR but this would be ridiculous so it is set to zero), but do you find it "fair" or "logical" to reward 0 points to someone that won......?
I enjoy playing Atomic Chess and i don't care too much about BKR, but i don't ignore it totally. My motivation to play against lower rated opponents, would become higher if i would gain some points (even 3-4) by winning...........
Is there any chance that this would change............?
It isn't reasonable.......

My third question is:
I see that the limit 2700 exist in various options when creating tournaments/games...etc. Is this the absolute BKR limit and nobody can have a BKR higher than this...........?

My fourth question is:
I have around 300 completed Backgammon games and 100 Hyper-Backgammon.
When i win or lose against an equal opponent at Backgammon, i gain or lose 8 points ALWAYS! When i win or lose against an equal opponent at Hyper-Backgammon, i gain or lose 19-25 points.......
Why is that happening.............?

My fifth question is:
What the "Activate pulldown game menu" does........?
I have activated today and nothing (obvious) changed.........
