How to estimate the gross potential revenue of a STR?

[Robert Johnson]

I've read "Short Term Rental, Long Term Wealth" and the direction is to use STR-specific data companies such as AirDna, but to focus more on the aggregate area data instead of individual property data. The other thing I seem to be seeing a lot is the ENEMY method.

For the ENEMY method in particular, I can grab 5 properties with the same number of bedrooms and bathrooms for consistency. I can look at airbnb and see how many days are blocked off in the upcoming 60 days for a rough occupancy rate, but given that many people don't book that far out this doesn't feel super reliable. Average daily rate is really difficult also because it's a different price for different days. It all feels like a ton of information and it's all over the place. 

I understand that STR income potential is highly variable but does anyone have a good resource to systematically go through and get some sort of a range?
