You seem to have bought into the internet myths about Lithium ion batteries. What you claim just isn't true. They do degrade over time but your figures are nuts.

My four year old rMBP has barely degraded at all and my 2.5 year old Nissan LEAF has barely degraded as well.

Try getting some more real world experience with these products before quoting a bunch of internet horseshit.
