Can attending a showcase at the wrong time hurt?

Judging from what I see on the self-described scouting organization's website, raw metrics will be public (they don't appear to "grade,") although it appears that this is an annual event for the top teams with this travel organization.  So assuming he stays with this team, he will do this same event next year.

Son is athletically -built , he is just rather long-limbed as of late, at 6'0, 170.    I am sure he will be more muscular and quite possibly taller (stronger, faster ) next year.  Although his focus is on improving and developing, his winter metrics were actually some of the top in our local organization.  Again, all feedback is appreciated, as I am trying to help son put this in perspective since this appears to be a team activity that he was asked to register for.

My son was 6’ 160 when he started doing major showcases and drawing attention. I’m sure coaches envisioned the potential when he developed into a 6’2”, 190 player.
