Scepticism about Vegetius\' analysis of the Late Roman Army?

[Tarbicus]

therefore, most of his statements and figures should be mistrusted.

Isn't one of his figures to do with the military step, and how far a legionary could march in so many hours? I've seen it said he got that wrong, ergo..., but it was proven on RAG a while ago that he was bang on, if the day is a long summer day, and the hours split between an early sunrise and late sundown - someone had a eureka moment. This involved a number of people (including me :roll: ) pacing up and down in the military pace with a stopwatch, then doing the calculations. I can't help but feel he's dismissed too readily, especially when a practical test of one of his statements debunks a more academic test.
