Thanks @mmaner for bringing this up!
- It means that I did not have had dropouts.
- It also means that those two cases with receivers in carbon battery enclosures had dropouts, but this also does not mean that the WAND does not work at all.
Regarding your point of the usage of “empirical method”, which you based on TWO cases with carbon enclosures is quiet funny - compared to the hundreds of WANDS around WITHOUT dropouts.
