Can you trust it though? It'd be trivially easy to do a 1x read, maybe 2x, and then fake the other 28 reads. And it'd be hard to catch someone doing this without doing another 30x read from someone you trust. There's famously a lot of cheating in medical research, it would be odd if everyone stopped the moment they left academia (there have been scandals with forensic labs cheating too, now that I think about it).
