Sure, there's all kinds of parameter-spread experiments that can be done, and it will be productive and rewarding to do them.
First though. for me, we need to find in as high resolution detail as possible just exactly what occurred around the R20 mesh, so we can logic out what may have happened, and thus be able to target them more reliably.
Lets hope that the lab will liaise with TM and get some really relevant and copious data.
Agreed: If we have caught a fish, let's analyze it as well as possible.
On the other hand: perhaps there are other fishers, who are in the opportunity to throw out their nets and able to see if they can catch anything.
