Since there has been some debate lately about the accuracy of calculators (no problem), then I figured I would post this thread as clarification.
For the Epson 5020, according to the PJC Calculator, the Epson 5020 is doing 33 fL at closest throw for a 110" screen.
This same calculator, claims the RS-45 is doing 18fL at closest throw.
OK so maybe they didn't use the best mode on the Epson, maybe they used a Dynamic mode.
They definitely used the BEST Mode of the JVC.
They did not disclose the modes however.
My calculator is reporting 21 fL for the JVC at closest throw, and about 18 fL for the Epson, both for best modes.
I can give many more examples like this.
I am not trying to diss their calculator, my point though is very simple, if you trust their numbers, then you are comparing different modes each time you change projectors.
Just my thoughts....
