Yep there are some inconsistencies, which are questionable, not disrepecting torres in any way, after doing this app i realised how hard it was to develop a tool like this. I think torres calc doesnt round off a number, so 31.5777777 will show as 31.57....whereas mine will show 31.58, and it rounds off all numbers so im stuck on whether it should be exactly like torres or abit off cos of that. from testing i thnk the worst i have been off is .08 and that was a fairly big box.
