as chance will be bigger and you can still save more satoshi.
What? Noo that is not true if you increment the more feee like 1.1 sat/vB insteat 1.0 sat/vB you don't save more satoshi, actually in that way you are going to spent more satoshis simple
math like 1.0 < 1.1
It's not really free to customize the increments of the fee because in Static option, you don't have an option to increase the decimal point, you can only choose from 1 sat/vbyte to 300 sat/vbyte. The only way to customize the decimal point is you're using ETA or Mempool option.
That depend of your software wallet if they give you te opcion to specify the exact amount of sat to be send and also the exact amount of sat to be use as fee you can increment by any decimal point value like:
First image at 1.0 sat/vB fee is 215 sat

Second image at 1.03 sat/vB fee is 220 sat

@OcTradism where is the saving here?
