I unterstand Chris, I should now check again what kind of sekonik types are actuall offered today.It may be my type is a little different to yours.Seconik Studio Deluxe was the name in the past.
Some colleges stated this type is no longer avaible - but it seams so that sekonik build it again due to much demand again.
Well as I staded before it is not often in use - only in cases when I have terrible doubts. AND even in that cases the metering showes exact what I have decided before....


..
Some oldfashioned long time retired colleges in the past were so much experienced that their messurements was made by their eyes : " Look at this scene here we have a classical 5,6 (100Asa - 1/50sec.) ..look at the background here we have a lost contrast of - 2,5 stops we wouldn't need more light therefore it is just fine to our emulsion....and now you should meter this scene come on hurry up..!!"
