Stus-List Backstay length and tension

When my two back stay turn buckles are tensioned to where I like them,
no adjuster pulled on, there is approx. 2" showing on each one on the
inside of the turn buckle.....I thread both sides of each turn buckle
When attaching to the back rail when stepping the mast, both are
loosened off approx. 1 1/2 inches of the 2" and they can be pinned no
I take my adjuster off the back stay each Fall and put it back on the
Spring.....it is not put back on until I have the two back stay(s) on
and tensioned so the adjuster has no part in getting the back stay pinned.
I don't have a halyard attached to the back rail or anywhere.....I don't
use a halyard.....never have.....with the mast in the mast step, blocked
at the base, the mast shimed in the collar, the forestay on, the shrouds
tensioned, my mast isn't going anywhere. A halyard is always added
protection but I will never use one.
Trusting this helps.
