Data sending optimisation

Thanks for the description Jamie. It was very thorough

X would be 0-1 bytes and Y would be 3-4

Or X would be 0-1 bytes and Y would be 2-3, even!

Oh sorry, my bad

One more question. What is signed/unsigned byte? Does it just remove sign of the value (+/-)?

Edit: Looks like "unsigned" feature "shifts" range of the value to the right by using first bit of the value as "numeral" instead of "significant". Am I right?

Signed uses the first bit to mean positive (0) or negative (1). Unsigned uses it as part of the number, so unsigned allows numbers double as high, but signed allows negative numbers.
