The meaning of words is determined by usage. Usage of words is determined by the meaning. This circular definition causes the inherent problem of language: words don't have inherent meaning. The best I can do is to attempt to use words in a way similar to the way that you use words, but I can only ever make an educated guess about how you use words, so it's never going to be perfect.

And from my perspective, I don't think it's unreasonable for me to expect you to try to understand what I'm trying to communicate, rather than attempting to force me to use different words. The burden of communication is shared by both speaker and listener.

“Faster” is not a well defined technical term. It is a piece of natural language that can easily refer to max time, mean time, P99, latency, throughput, price per watt, etc. depending on context.
