Hi @stefaniebutland , I updated the GitHub Clinic timings to match the updates for Fred Hutch.

I also poked around with the 1h31 min timing and couldn't fix it; it seems this is a known issue that we'll have to dig into more deeply with dedicated time. It's only incorrect at that first place up top so if we can change that one by hand we'll be ok for now

note to self: also consider a function where you check the call before actually building it
