Several decades older? Laughable! The Incas themselves said they had no idea who built it; it was already there when they arrived.
“Machu Picchu, the famous 15th-century Inca site in southern Peru, is up to several decades older than previously thought...”
Glad they got that straightened out; now we can all sleep better. That few decades correction out of 700 years really means a lot.
Trust the (repeatedly updated) science.
The change in workmanship is obvious at many, if not all, of the Inca ancient sites.
The base build is of high quality, massive stones, then built on top of that is low quality small stone.
Makes it fair obvious that the Inca came in as squatters on builds that were already long in existence.
I ran across this discovery when looking at pre-inca civilization in SoAm.
The layout is remarkably like Machu except no buildings of note. Did the Perdidaians move to Machu or did the Machuians move to Perdida? Cousins? Prior civilization?

The intransigence of archaeology never ceases to amaze me.
