The suffixes for large numbers are not intuitive.
Hard to know what "3STg" and the like means...
Maybe just stick to an alphabet sort of suffixes like 1, 10, 100, 1a, 10a, 100a, 1b, etc...
Or better yet, just use scientific "E" notation: https://en.wikipedia.org/wiki/Scientific_notation#E_notation like 1, 10, 100, 1e3, 1e4, 1e5, etc...
