It's a pretty normal amount from what I see. The bag is full but I don't have to struggle to jam anything in like I see a good amount of people have to do.
It's 18 excluding my dupe putters for extra putting practice and a 2 other driver dupes I don't need to bag but do for extra throws and excluding 1-2 trial discs I'm deciding on if they will replace something else or could be additions.
E.g., I just got an Champ Eagle X because my Champ Eagle is only slightly OS and I wanted a beefy 7 speed slot, so now I have four seven speeds when I was normally planning on 3, but I might keep both Eagle's since the jump from really beefy to straight within a speed group is a pretty big jump with nothing between it. But I could also just go up to 9 speed when I need something beefy and so if I want to simplify I might choose to do that.
It's a fairly symmetrical build design: X-OS | OS | straight / slightly US | US down the chart for the different speed groups.
I chose this strategy without much influence, it wasn't because I saw pros have 20+ discs or because people told me to get more discs. It was because I wanted to have a good range of clear stability divisions at each speed and to learn all shot shapes both BH and FH. Later on Ezra A and Holyn both came out with a bag building strategy vid where they described this symmetrical approach. Holyn recommended trying to fill the straight slot first at each speed group so that if it's more or less stable than desired it just fills the neighboring stability slot then you fill in the others.
Of course most average players only throw like two different shots, so there's much less use in having more discs in that case.
The flight chart is weirdly off for the Watt and Hex and is missing the Innova IT.
