Watching this streamer use Showdex on Gen 9 National Dex, we noticed that the calc for Pin Missile was incorrect since his Heracross-Mega still had the Swarm ability instead of Skill Link, which makes multi-hit moves hit the max amount of times.
While Heracross (non-mega'd) can have either Swarm, Guts or Moxie, Heracross-Mega only gets Skill Link.
Because of this, Lazosful ended up hitting the Close Combat against his opponent's Umbreon (96.4 - 114.2%) since the Calcdex told him that Pin Missile (60.9 - 73%) probably wasn't going to OHKO. With Skill Link, his Pin Missile would've done 101.5 - 121.8%.

Sorry about that Lazosful!
