Dear Elric;
Of course!, that it’s for everybody allowed to believe what ever everybody likes, for EPA too!
But it’s at least of the same true! that every systematically error is, now and for ever!, a systematically Mistake! — absolutely independent who ever is doing it!
Using a not measured, or a forced Point in any Statistics, and Calibration is Statistics, is there wile violating the tiniest Statistics and every Logic too!
Quintessence:
Everybody who is doing it anyway, is not only disqualifying the Calibration she/he/it just did!
It’s also not with, but violating the Proverb:
“Wer misst, misst Mist!, was weiter nicht schlimm ….. . ”

Good Luck!
