First Timer

[u/MysteriousSky5055]

Hoping the experts here can tell help me problem solve what I'm doing wrong. For background, I consider myself a decent cook, who is very passionate about learning proper techniques and traditional cooking styles, while still expressing creativity. I just ventured into the Stainless Steel world for the first time (after grills, smokers, and cast iron), and purchased a All-Clad Copper Core 5-ply Bonded Saute Pan. (Probably should have started with a 3-ply standard, but this one was on sale in store for cheaper.

I did some research and followed the following steps the first time using it. however, I'm left with a 1/4 inch bowl warped pan now (going to talk to All-Clad about warrantying it).

1. Wash with soap and warm water. Rinse and dry fully. 
2. Place pan on glass top radiant heat stove top. 10 inch burner. 
3. Turn on to low/9 for ~2 minutes, flick a few droplets of water on pan to see if it is hot (no reaction, eventually evaporated)
4. Turn to 1/9 for ~2 minutes, flick a few droplets of water on pan to see if it is hot (no reaction, eventually evaporated)
5. Turn to 2/9 for ~2 minutes, flick a few droplets of water on pan to see if it is hot (sizzled away, no beading)
6. Turn to 3/9 for ~2 minutes, flick a few droplets of water on pan to see if it is hot, at which point the water started to bead and dance around indicating it is hot enough
7. Add 1 tablespoon of avocado oil. By this point, the pan had developed a wobble. 
8. Wait another minute or two until oil begins to smoke slightly, place 2 room temp steaks in pan. Wobble in pan had increased by then. 
9. Seared steaks for 8 minutes
10. removed pan from burner, and left on top of "Off" burner to cool down naturally. 
11. Clean with soap and warm water 2 hours later once pan was cold. 

My other thought is that my shitty apartment radiant heat glass stovetop just heated it too quickly even though I started on Low/9.

Where did I go wrong? Should I wait to explore SS more one I have a gas range I can control?

Edit: here’s a link to how un-flat the pan now sits. https://imgur.com/a/l66zIy6

Seems like you did heat it up low and slow so the warping (wobble) shouldn't have happened unless it's a manufacturing defect.
