Let me help you understand probability.

If something had 0.75 chance and now it is twice as likely (or one times more likely), it doesn't mean it has 1.5 chance.

Think of it as a ratio, 0.75 is on average every 1+3 times there are 3 times. Now twice as likely is now on average every 1+3*2 times there are 3*2 times or 6/7. To find probability p, x times as likely is px /(1 -p +px) or ((p^-1 -1)x^-1 +1)^-1.

Back to the Easter Neneko problem. It was 0.15 and now it is 0.1. Solve ((0.15^-1 -1)x^-1 +1)^-1 =0.1, we find x =17/27. x is how many times as likely, to find less likely, subtract 1 then times -1, which is 10/27 about 0.37.

Easter Neneko is 0.37 times less than original Neneko.
