Stun Time

Since Lances transition to 3 hit, and since they are classified as 'Very-Slow', wouldn't the stun time be 1.65 sec?

What rank 9 Lance Mastery really does it lower it's knockdown gauge addition just enough so you can deal 3 hits without having to delay like N+1. It's not a true 3-hit weapon as you can't N+1 to get 4 hits without the enemy coming out of stun. At any rate, even 2.3 stun time is a liability since you are vulnerable after a lance combo...

After continued use of my lance, I believe the stun time is actually closer around 1.8-2 seconds. I'll have to get a stopwatch or something to record this more accurately, but it's definitely not stunning for as long as my gladius.
