primary spring height question

[Groomerdriver]

when the chart says 87.5 mm (?) for a spring height, what is the +/- tolerance?

if a spring is worn, will the spring likely be taller (extended) or shorter (compressed)?

the primary spring from my 2005 Vector (4300 miles) is supposed to be a Y-S-Y and it now measures approx. 90mm. at first I thought it was a Y-W-Y spring that is supposed to be 91mm, so I thought I was OK at first.

any help is appreciated!

A new spring is $20. From my experience, Yammy springs tend to sack out with time. Won't hurt to replace it.
