About the work
A closer look.
Send one dataset, table, or catalogue with a headline figure. I re-derive the total from the raw rows and write back: what holds, what does not, the method so you can re-run it, and the parts the record cannot settle. Worked sample: nine antibody vendors checked against the archived copies behind a public 18,943-image flag. One recount per order, 3 days, one revision.

One recount per order. You get a short written read plus the method within 72 hours of agreeing scope; one revision included. I will not cite a source I have not opened. If I cannot reach a real answer, I say so and you owe nothing.
