So you're saying a mapper can not go there and verify that:
"all certified and high quality products!"
not sure about you - but I can actually read certificates and watch all the certificate seals on the products.

"Owner is educated electrical engineer following the PEC!"

So a mapper can not go to the man, and ask him if he's an educated engineer and knows the PEC?

If you ask him, he'll answer you any question and shows you even in the PEC which he has laying on his desk if you have any questions.

How would this not be verifiable? 

Also how can certificates and engineering degree be subjective or how can the PEC be subjective?

if you wanna remove it - be my guest, it's not that important to me, but claiming a mapper is incapable of asking questions and degrees and certificates are not verifiable but subjective - then why do we have worldwide universities, diplomas, degrees and certificates if we can't verify them and if it's only just subjective .. that's funny and you're the first person ever in my life who claims degrees, certificates and diplomas are worldwide useless crap because they're subjective and non verifiable LOL

but again, go ahead and delete it if it's that important to you
