Sweater-grading math: fun? Or crazy-making?

How about some numbers? So I looked up the standard measurements for German baby clothing sizes and multiplied those chest measurements by my gauge (2.8sts/cm, if you must know) and got... some odd results. Frex, size 80 (10-12 months) and size 86 (13-18 months) came out pretty much the same, so I have all these little two-month ranges and then suddenly this sweater will fit your infant for nearly a year. That seems unlikely. Quite a few of these sizes seem profoundly unlikely, actually.

Bear in mind that all of these numbers were achieved with an online baby size chart and the calculator in my phone. No knitting was perpetrated on any of these sizes except for the smallest one. 

So yeah, I'll probably need some test knitters.
