I think my point is that the odds that Rossi or IH were trying to sneak something in are terrible. The odds of being caught it it are extremely high.
These were not single particles that were tested: they were several particles and tested by two methods, by surface and total digestion methods, and are in agreement. The accidental selected random particle theory collapses on this point.
The odds of the selection of a group of particles, on two occasions, showing the anticipated (to some degree of) change, in the right order by accident are implausibly low.
