Allow more ChatGPT4 credits for shorter messages trade off?

This is regarding the current limit of 40 messages per 3 hours on a paid subscription with ChatGPT on GPT4.

I understand the need for limits, but I’m wondering if there is time for OpenAI to develop some wiggle room. Could we instead base usage limits on the size of the conversation instead? For example, I’d still get 40 messages per 3 hours, but if all my answers are half the size, I’d actually get 80 messages per 3 hours, etc. The justification is that if we ask for less verbose answers, we’re using less processing power right? This is more flexible and fair in my opinion, but I don’t understand your infrastructure etc so maybe I’m mistaken
