Help! From Zero to Hero and not sure what to do...

Third time building a starter from scratch (First 2 tries could have landed me in prison for sourdough abuse).

One is Gold Medal AP flour
One is H Mills Rye

Both are at 200g currently

Both hit DAY 8 last Saturday and I baked with them, VERY successful.

As soon as I pulled the starter needed for baking, I fed them and tucked them immediately into the fridge with fairly tight lids.  I was so excited to bake and share the bread that I didn't even look at them until today.

They were listless looking and I thought I killed them.  2 potential bad choices on my part:  1. put in fridge on day 8, and 2. didn't wait an hour or so after feeding and put straight in the fridge.

So this afternoon, around 4 PM, I took them out and opened them up (I want to bake Saturday and was freaking out).  They really didn't look bad at all.  I let them sit for an hour and gave them a stir, leaving them out on the counter (68 F in our house).  It is after 10 PM now and they are more than triple in size.

I guess they were healthier than I thought???  While this is very cool, I don't want to screw up my Saturday bake, so what should I do?  They have yet to flatten out.  Should I leave them all night?  Feed and fridge and relax til Friday?  Sorry, this is new ground for me, I'm used to killing them within 5 days :)

thanks!
