Unit upgrades in exported battles

[Shad]

I like to fight major battles and after reaching late-game started to wonder. There are 2 different types upgrades you can do, and I'm not sure how they work with exported battles.

1. Unit reforms. Some of there change the unit types i.e. upgraded macedonian heavy infantry change from armored hoplites to imitation legionaires. Other units like javelinmen or light cavalry do not appear to change. Are they affected by upgrades at all in exported battles?

2. Master armorer/fletcher/stables. These upgrades I have not seen any obvious changes. I remember reading somewhere it improves the conversion ratio between units, but not really clear how much by. Would be nice to know to estimate whether it's worth keeping an army in the back for a couple dozen turns.

In both cases the conversion leads to the same unit, improved by a reform or by a master crafter. So in this case this usually translate in a slightly better Quality Modifier (it can go above 100).
Then, for the rest I can't really say in fact, this quality modifier is sent to Field of Glory and will alter the chance the unit you see has more elan, experience, etc. but I can't comment on the exact formula, this is on FOG side. This is probabilistic in any case.

My estimate is that it is not worth the time, if your only criteria is the tactical battle in FOG. It is if you want them to fight in Empires.
