Am I reading this correctly? FM Data Sheet 8-9 Table 8

[SprinklerDesigner2]

I got a little job where the ceiling is 16'-6" and FM Global directed me to FM Data Sheet 8-9 Table 8

I know I am reading this correctly but the pressures seem awfully low to me.

Using K25.2 EC https://www.vikinggroupinc.com/sites/default/files/2025-03/121610.pdf all I need is 6 heads discharging at 22 psi with spacing up to 14'x14'?

Or 12 K16.8 ESFR pendent sprinklers at 13 psi?

I know that is the correct answers but the pressures just seem awfully low for a building with a peak at 26'-6".

For 26'-6" peak I am reading 6 x 25.2EC for 30 psi or any other combination at the same row (i.e. h≤30').

Note, all green option require 250 gpm hose allowance and 1-hr duration.
