I wasn't trying to talk past you. My original comment was that a specific complaint about the amount owed being 40% after 4 weeks, despite 4 weeks not representing 40% of the program, could be addressed by tying payment directly to portion of curriculum covered. You responded that this is how it works, but you redefined the denominator in the proportion from the original complaint.
I don't think you're doing this in bad faith, I'm legitimately just trying to point out a response something that is clearly a frustration isn't translating how you intended.
