In my inventory I have a steel chest plate of minor health (Item A) that had a rating of 75 and I found a steel-plated chestplate (Item that had a rating of over 100. So i went to disenchant "A" so I can enchant "B" with the health but the moment I disenchant "A", the values of the "B" armor drops to 90!! I don't get it, i have reloaded, dropped "B" on the floor or given it to a companion before I do the disechant process but same thing no matter what, the value of the "B" drops. any idea on whats going on?? This also has nothing to do with the equipped value in case that changes due to perks. Both items are unequiped, I look at the values, I disenchant "A" and the value of "B" drops.

I'm not sure but your skill levels may be having something to do with it, what's your enchanting and smithing skills at?
