Hickey the "Armpit Assassin" doesn't work.
Powers would, if he possessed a rifle instead of a camera.

In the Donahue drawing Donahue shows SSA McIntyre 6'1" (73") high standing on a 9" running board, which adds to 82".
This is based on the windshield of Queen Mary being 60" high.
Hickey was a tall dude say 6'2" standing on the 10" floor, which makes the top of his head 84" if standing erect (as shown by the oval that i drew).
The Bronson footage shows that the top of Hickey's head at B07 was a half head lower than if fully erect (say 74")(head is 10")(see earlier in this thread).
Notice that the oval head is drawn further forward than the Hickey drawn by Donahue -- his Hickey is standing on the seat -- my oval head is based on Hickey standing on the floor.
The black line that i drew to show the AR15 trajectory is based on the inshoot on JFK's head being 6" below the 60" windshield -- & i said that the line was 63" high at about the butt of the AR15 -- the line is drawn ok, but the 63" is wrong, it should say 62".
As can be seen if Hickey were standing fully erect he would have to have the AR15 say 4" below chest height -- but if not fully erect then say 1" above chest height.
Your overlay of the guy holding a rifle is pretty much correct for what Hickey needed, height wize, but aint necessarily correct in the horizontal -- in the horizontal Hickey might have had his AR15 tucked back under his (right) arm (not left), but more likely Hickey held his AR15 out in front a bit.
In fact i estimate that the muzzle of the AR15 was 28" back from the windshield (& the AR15 was say 39" long).
And your guy needs to be shrunk to 5/8th to properly model Hickey (& then shrunk to 4/8th horizontally)(koz i have shrunk my horizontal dimensions).
I drew the inshoot 6" below the level of the windshield of Queen Mary (60") -- which makes the inshoot 54" above the street.
Actually in this (very early) drawing of mine i drew the inshoot 6" below the blue line joining the 60" Queen Mary windshield to the 59" JFKlimo windshield -- but in later drawings i drew the inshoot 6" below a horizontal line from the 60" QM windshield -- so, in the above drawing the inshoot is more like 53" above the street, ie 7" below the 60".
Also, for simplicity, all of this is based on Elm St being level, rather than its true 3.3 deg or something (karnt remember).
But, that 6"/54"aint critical -- the inshoot is say 211" in front of the windshield -- & the muzzle is say 28" behind the windshield -- which is a ratio of 7.5 to 1.
Hence the muzzle had to be 1" above the windshield if the inshoot was 7.5" below -- not a problem.
When i say 1" above i mean 1" plus a half of 0.223" (ie 1.112").
But u say that that duznt work -- please explain.
I should add that the only problem that i really had was the dent in the chrome trim -- clearly from Hickey's 2nd last shot of his auto burst --
but recently i realized that that shot went over the windshield of Queen Mary & then under the divider/rollbar of the JFKlimo -- the divider is higher than the chrome trim -- so, everything fell into place -- & the problem was not what the so-called experts said was the problem, ie that the AR15 had to be very high, no,
the problem was that the AR15 had to be higher than the windshield but lower than the divider, a small small window.The other earlier shots of the burst had to go over or between the upturned sun vizors on the JFKlimo.
