I'd guess a Magnesium deficiency is to blame.

How likely is it, that all 3 sellers, one of them a cycad-pro, made this fertilisation-mistake over many years, and then I continued with the same mistake?

A genetic predisposition to Magnesium or Manganese deficiencies is totally reasonable.  Some palms get Magnesium deficiencies much worse than others, and there's variation between palms of the same species too.  The brown tips on your plant look like slight underwatering, which can also contribute to leaf tip yellowing followed by tip browning and leaf tip death.  To stop the "Aurea" effect it might just need an unusually large amount of Mn and Mg, or a little bit more water.  That doesn't necessarily make it variegation.

My ~10 Revoluta have about a 3-4 month span between flushes.  I have a small Revoluta pup in the front yard that does this exact same "aurea" yellowed leaf tips.  It starts going yellow tips about a month or so after the flush hardens off, approximately at the same time that the leaves start pushing downwards as the caudex starts to expand for the next flush.  I'll take some pictures of it this spring.  If it does this consistently in the spring I'll toss a bunch of fertilizer at it and see what happens.

Show me a picture.
