I suspect he is just going by the weight. The VA depends partly on how hot 
you are prepared to run the transformer. If you assume that most 
ordinary laminated transformers are pretty similar in geometry, you cant
go far wrong. Especially as all he has to do is guarantee that a 
particular transformer will give x amps without getting 'too' hot.
If he was completely fanatical he could make a load out of old stove elements.
