I'll reply here (because I simultaneously replied to your other comment but removed it). I also thought it was funny we had come to opposite conclusions based on the same data.

Type out "Bottom-up" in excalidraw, it matches perfectly. The lower case `t` has a curl on the bottom in the diagram too.

EDIT: Re Edit:

No worries about noise. I had a good chuckle with our near simultaneous replies which was nice after the way our project has been going this year.
