You're still engaging in pure speculation, since (1) a properly-fitting MIPS helmet might've given even better protection, and/or (2) even the poorly-fitting Giro might've given even better protection. There's a possibility that either (1) or (2) might have prevented your minor concussion. The only way to know for sure is for you to wear the GIRO and perform the crash all over again.
