Comparing two labs on the same batch, results inside

take it or leave it here, the framing aged well

two things:

• OP answers most of it
• in my case, reader beware

your batch id aged badly, given that clearly biased

For context: your batch id confirmed what I thought.

flagging the second paragraph answers most of it, no expert

fine, bullets because paragraphs feel too committal:

1. 01timing matters
2. 02baseline matters more
3. 03and this last one negotiable

noting op is doing a lot of work
