Oh, I’m playing Warframe now?

I am saving training if my next squad mission comes back and they don’t reach 20 they are 15 right now and in 3 hours they will return. I might just spam training for the last few levels.

Ummmm, you aren't saving anything though. You can only train 3 times a day and it's reset daily, you're just throwing exp out the window. Train them the 3 times then send them out for the rest of the day.
