Weight loss/gain forecaster incorrect + typo

[k4t]

I've been testing out the calculator while setting up my account.
Quoted below is the output from my weight loss forecaster today if I put in 1200 cal eaten, TDEE 1633, current weight 57.6kg and goal weight 47kg. I think the daily/weekly/monthly/yearly calculations are pretty accurate (as far as these estimates can be) but I don't understand how they can translate into a goal weight achieved in late 2013! Even taking into account a falling TDEE with weight loss an almost three year time-frame still seems wrong to me.

Also note the typo in the final sentence. Should be loss.
