[CAUT] Which side to yank the butterfly spring?

[Ed Sutton]

I'm reconditioning a set of wippens, and have them off the stack. As I was cleaning gunk out of the rep lever groove and cleaning the spring tip, I looked under the lever, at the allignment of the spring coil, and it occured to me that when the spring is snapped out of the groove and over to the bass side of the lever, the coil can open easily when you yank on the tip of the spring to make it stronger. Snap it out to the treble side and it jams against the underside of the rep lever when you pull. 

It seems to me this would be a good policy - snap the spring out to the bass side when adjusting spring tension. 

I don't recall reading or being taught to do it this way. Have I missed something, or am I imagining that something insignificant really matters?
