Hello.
I've noticed that "Site Survey" infusion show incorrect Quality info, cause it's produced from iwlist utility, where the maximum quality is 70, not 100 as it's suggested in infusion interface.
Small changes to iwlist_parser.php solves the problem.
I'm not very good at PHP, but here's my way:
$ergebnis[$device][$cell]['Quality'] = trim(number_format (substr($zeile, $first_eq_pos + 1, $slash_pos - 1) * 100 / 70, 0));
P.S. I've not found "Site Survey" topic and have made it myself, i hope author of infusion will see it.
