RPM spindle length was dead on at 113, which it was marked as. 2mm error on 110mm spindle for a machined part is very poor precision. If a UN55 113mm version has that imprecison, then what is the point of having both 110 and 113 mm models, as one 110mm sample may be equal to a 113mm sample? Or are all UN55 110mm models 112mm?
