Indeed, I've seen Mr Kindt's site over a decade ago. You'll find very little difference between putting on 14th and 16th century armor by yourself:
* the cuirass may require assistance on either one, but both are often single chest/back units without faulds or tassets (esp early-mid 14th),
* the arm harness would be pointed to the arming clothes on both,
* the 14th C gorget / bevor are often similar in strapping,
* the upper legs would be pointed to arming clothes the same,
* the greaves & sabatons are the same,
* gauntlets are of course easy either way
The armor that gets really difficult to put on your by yourself is late 16th cent italian, especially if it has the additional reinforcing plates, with the angel wing pauldrons, armet w/gorget + wrapper, massive cuirass w/multiple faulds & tassets, etc - of which german gothic doesn't have.
