The rip by annas archive is 170kbps ogg for most of the songs (most meaning listening probability, not quantifying numbers.).
Furthermore 96kbps is more than enough for casual listeners. You may hear a difference but most people wont care tbh.
Or e.g. in my last appartment we had an weird electrical water heater that didn’t work that well. I was able to easily estimate the extra cost it procured by estimating water volume, temperature difference and electrical price, most annoying par was converting from joule to calories because it is not base 10. (would have taken >3years so not worth it for me)
I do stuff like this all the time. Like if i bought a pool i wanted to estimates how much water it needes to estimate all the follow up costs, if i am cooking something i often switch between kg and g, if am measuring things i switch between cm, m and mm depending on what i am currently measuring all the time. E.g. i needed a new working plate in my kitchen, i wanted it precut to fit exactly in after moving some cabinets while still aligning the sink. The whole space was measured in meters, but the individual cuts were all measured in milimeters. I was able to do all of that in 5 minutes with one piece of paper for sketching and my head. (And it fitted down to the milimeter in the end).
While i agree with the sentiment v-bucks are not 100% profit. People buy v-bucks for skins, these skins have to be produced by people who typically don’t do that for free. And for ongoing sells of v-bucks fortnite has to get regular updates, one of the selling points of fortnite are the regular seasons and events, these are not free to produce. Obviously they do all of this to increase profit but 100% profit ratio is a strange take.
