7.25 compared to our fake it estimate of 10 isn't that far off and is believable.
One of the other charts on that site shows some Ah estimates at 1/10th as well so glad to see we were in the ballpark.
But, I wonder what their Ah rating is based on in terms of discharge hours because there's no way those Ah ratings are for 20 hours, which is the standard discharge rate for the posted Ah on deep cycles.
You could literally establish your own 20 hour discharge Ah rating for the starter battery by simply finding out how many amps the full charge battery will deliver steadily until it is at 12.00 volts. Actually, that is pretty useful to know that. Then the same for how long it will power x amps down to 12 over 10 hours and then the 5 hour rating.
For test equipment, battery capacitor analyzers, shorting type testers, etc. - basically, there isn't one that ever gives an accurate number and they're all flawed but are good enough to see maybe the parking lot of the ballpark. B & K battery capacity analyzer was tweaked by their company to my understanding at a certain point because of the feedback that Bedini gave them.
Here is some battery equipment that everyone in this field should have - it gives a constant current discharge based on your specs and graphs it so you can actually see exactly what your battery is providing, etc. and then when you charge the battery, it can graph that too so you can see when it's actually charged. These are a MUST HAVE - I still have a few.

All the charge/discharge tests for all the chargers and charge controllers here were done with that CBA IV - https://teslachargers.com/
You can use any resistive load like ohmite power resistors, incandescent bulbs, etc. that you calculate to give you the desired amp draw and measure the time - you don't need this equipment, but it is a time saver, you don't have to babysit it, etc.
