Deductions & credits

Volvo girl, I would argue that I've provided plenty of data that demonstrates this is a bug:

-- exactly the same data, when put in TT and other software or manually calculated has continually shown TT to be producing a wildly different result.

 

How do you imagine this is nothing other than a bug when it is LITERALLY the SAME data? 

 

Like I stated before, I work in software development, I am intimately aware of issues like this and if 1 software or algorithm is producing different results, you investigate why and correct the issue.
