I have pmed both squatdr and adarqui before and both were very nice and helpfull (its not relevant but says about character). As far as numbers I tend to not believe pretty much anyone after hearing ppls 350-400 squats and then seeing not even a quarter squat in person, or checking out peoples so called 37-38 inch verticals (sometimes it seems like people just pick a random number as to how high they think they jump).
On top of that for squats at least there are powerlifting competitions so if someone squated y amount in a competition I don’t have any reason to doubt them, however no comp for vertical jump and all the tests are done by strength coaches of the athletes who obviously have quite a bit to gain from inflated numbers as a result it got out of hand with everyone having a 40 inch verts.
Hell when I test my vertical on different equipment I always get a different reading between 2 to 3 inches which is pretty significant as far as vertical goes and I am just testing it for myself so I got nothing to gain.
Having said all that when a person claims world record performance outside of competition in any event, a lot of backing up needs to be done with a ton different angles to even be considered real.
On the other hand I don’t care all that much what the guy really jumps (slightly because it would be nice to know what a world record would really be but like I said there are no competitions therefor no two peoples results would be the same), I don’t know him, he is not my coach, and the stuff I asked him about had nothing to do with vertical jumping or even training.
