So, I’ve seen a couple of topics on this, but unfortunately none of them are simple enough for my dumb brain. Can someone help me understand how the different autocasting options work? Note, this isn’t a question about how to unlock them; I’m on R24 and I’ve got all the pre-ascension autocast upgrades. My questions, I think, are these:

• What is the difference between the bronze, silver and gold autocast options?
• Do any of those three options work differently with the mana bar slider?
  

I think if I can get these answered it will round out my understanding on the topic. I appreciate any help in advance!

Edit: /u/loseallthetime below has provided clarification, thanks a ton to him! This makes full-mana TC combos MUCH easier.
