I thought the calculation from PTOptimiser output without octave 
could be turned into a javascript calculator in the tutorial itself.

...so I added it about 3/4 of the way down the tutorial.

Though playing with the values, it seems to create wrong output.  
Shouldn't this part of your calculation be the other way around?

  scale = hfov_green / hfov_red

ie. like this:

  scale = hfov_red / hfov_green

Too late here to think, I may be wrong.
