Am I doing something wrong?
As far as I understand, the 1% is per month, not per year, dear fillippone. Therefore the calculation should be like this:
Daily interest = capital * monthly interest / 30.
The yearly interest is 12%, not 1%.
As far as I see, Whirlwind gave this example of calculation:
The rewards are compounding, every day you receive 1%/30 of your total Note balance and that includes Anonymity Mining distributions.
Oh, I got the daycount wrong, apparently:360 Even better.
Regarding the combustion.
My computation considering 12% yearly yield daily compounded:
Daily interest=capital*annual interest*days/360
Hence:
0.00046059 BTC*0.12*1/360≈ 0.00000015353 (15 Satoshi, still)
Using your computations:
Daily interest=capital*monthly interest*days/30
Hence:
0.00046059 BTC*0.01*1/30≈ 0.0000001535
Exact same result... As expected.
