I bought a Miche advanced crankset with BB and threw them onto my project bike to find there was some play in the chainring. I'm aware that chainrings aren't perfectly round but I need a second opinion on this (or third, fourth etc). Now am I crazy or is this chainring machined wrong? (see video)

ANY info or advice would be awesome.
