Default PAC 1243 Valve Springs

Got a new set of PAC 1243 springs and I checked half of the springs and decided to stop because I think I will be returning the springs.

Installing them at 1.850 and 2.215 open

On the seat they range from 220 to 272
Open they range from 608 to 618

The open pressure is pretty consistent but on the seat the pressures are all over the place. An interesting thing is the spring that had the lowest pressure on the seat had the highest open pressure. Has anyone else had this problem?
