How so? Counted the characters manually and came up with 200+ (don’t recall the exact amount). Let’s call it 200 to make the numbers easy. 200 * 0.1 = 20 sats

Possibly you are using the number of input characters rather than output characters? If so, that is great! In that case, I can see how you get to 8.2 as there are fewer characters in the input.
