Even 15/20ug is quite a bit, which I would sometimes consider a minidose (depending on the setting).
I detect even down to 5-7ug LSD that I'm dosed (though I'm quite experienced with all kinds of dosages).
75ug is definitely tripping-level. No way someone couldn't detect that they are dosed, just the contrast/visual-enhancing qualities alone should be enough to detect that, maybe even some LSD-typical distortions can occur at that dose...
