Yes, this is OT.

The standard says you can send just LSB, just MSB, or LSB + MSB for the parameter number, and then change the parameter value with either Data Increment,m Data Decrement, or Data Entry -- which is a 14-bit controller, so it can be either MSB or MSB followed by LSB. So yes, a fair amount of variation there, and actually, there is a lot of inconsistency in the whole LSB/MSB reception area in product implementations.
Is it mandatory to always set the parameter number before changing the parameter, or is it also allowed to set the parameter number once and then after that send multiple data increment/decrement/entry commands?
How does a receiver of a data entry command know if a LSB will follow a MSB?
If only MSB or MSB+LSB is allowed, why did they not choose MSB or LSB+MSB?
