From an econometrics stand point, your regression curive is kinda flawed as the top 6 data point are very far of the rest of the group and thus have too much influence on its determination.
Nice idea tho!
Yes the points in the uppper right hand corner determine the slope. Not driven by a single point rather a cluster of points most determined by the new Great Whites. Besides from the Great Whites, the most expensive (on a mass basis) lens are specialized lens (14mm, 17 and 24 TS-E, 8-15 fisheye, 50 F1.2) with the exception of the 24-70 MII.
If you look at the data table you see several trends. Key is new lens tend to have higher prices ($ / mass) trended around $1,200 / pound.
Here are the 10 top lens based upon price / pound. Half are great white, 4 out of the 5 five are specialized lens, the last is the 24-70 MII. Could this indicate future price trend at Canon?
EF 8-15mm f/4L Fisheye USM $1,260
TS-E 24mm f/3.5L II $1,280
EF 400mm f/2.8L IS II USM $1,297
EF 24-70mm f/2.8L II USM $1,300
EF 300mm f/2.8L IS II USM $1,314
EF 800mm f/5.6L IS USM $1,337
TS-E 17mm f/4L $1,384
EF 500mm f/4L IS II USM $1,480
EF 600mm f/4L IS II USM $1,482
EF 14mm f/2.8L II USM $1,660
