"Correct me if I'm wrong -"
Well, okay.
You are 50% correct.
Negative on the slack media. EOU specifies the ideal test media tension with the ATF series is 100g. That's the same as 17.63 US quarter dollar coins or 20 US nickel coins. Not much tension, but not slack.
You are correct on over tensioned media. Over tensioned media can indicate sharper than normal readings. Test clips for instance read 20% too sharp. This can be normalized by wiggling the legs holding the media to loosen the media slightly or normalizing the reading by -20%.
That said, it's not all that sensitive or critical and you don't need to over-think it. When threading the media, just pull it across and gently remove the slack.
Slicing the media instead of push cutting will cause over sharp readings. Proper technique is to slowly push cut the media with the blade perpendicular to the media.
