Negative Fleet Training Question

[Brighteous (OP)]

Well after a couple years of lurking on this forum I may have finally found a situation that I can't find an answer to.  Which is really a testament to the community so thank you everyone.

My fleet training goes negative when deployment is exceeded in a training admin command. 

The current situation is I has some short range small ships in Sol and I thought I'd leave them in a training fleet with standing orders to overhaul and resupply.  Unfortunately I forgot about them until I needed them (of course) and imagine my horror that they were about -50% for training and also well over their deployment.  It appears that if i manually move them out of a Training Admin Command before deployment is exceeded they overhaul as ordered and as long as I don't exceed deployment the training progress stays positive.  One thing I noticed is while overhauling the effects are counted every 4 days will the maintenance and deployment counter is daily.  So perhaps because of my ship design it is simply wearing out faster than it can overhaul?  I know training fleets do cause increase maintenance but I can't tell if leaving ships in a training admin command is not possible or if my design stinks.   Switching short deployment ships in and out of Training manually seems cumbersome but perhaps that is intended because realistically nonstop training isn't feasible.

Admittedly I'd normally experiment more but because of the dire situation in Sol at the moment I don't have more ships to experiment with and frankly it might be faster to build new ships at 0% then try to train up from -50%.

So I guess the questions is am I missing a mechanic on how training works, or maybe an order or standing order to give the fleet that would prevent this? Or is really as simple I parked my fleet in training admin too long burnt them all out?

Keep fighters and FACs inside a hangar during training to avoid this.

What about larger ships? Fighters and FACs have to be under 500 tons correct?

FACs can go up to 1000 tons (any higher, and you have to add a bridge) and any ship can go into a sufficiently large hangar, which will freeze its deployment clock if the hangar is commercial and also maint clock if the hangar is military. I use my old carriers for training purposes, but in theory, a commercial hangar space station should work fine as long as the ships within can perform their most expensive repair by themselves. Not sure what's up with the negative training though, to my knowledge the fleet training rate past rated deployment will slow down because of the morale modifier, but it can never go negative.

Fleet Training often goes negative if a fleet spends too long on active duty say 26 months when built for 7 months deployment, I have had several training fleets drop to negative levels when I fail to spot they have passed their deployment time and leave them deployed for several years. I believe the same effect occures for a warship deplyed on normal duties for too long, but I usually notice that so I am not certain
