Here is what I see when looking at the RIDE site.

Chariho has it's own $ amount, as do the individual towns that make it up.
Bristol-Warren and Exeter-West Grenwich do not.
You mention as supporting documentation "intent" and other articles. But, I don't see anywhere you have posted language from the law (sorry if I'm missing it). Anyone can write their opinion on it, but that doesn't make it correct.
Can you point directly to the law where it says Bristol gets X, Warren gets Y? It sounds from what you post, it is up to the treasurer. So, you're saying the treasurer should do it differently because you want it to be done differently because it benefits warren (and I understand, that's your job).
