John,
Your scaling is pretty spot on to me.
Some eyepieces in diffrent lines are better than others.
Take the Meade's UWA 4000 series. I have found the 14mm and 8.8mm far and away better than the others.
I would give the 8.8 and 14mm 9.5/10. The others 6.5/10. Thats to me going by how you would rate them.
You took on a big thing scaling eyepieces as its very personal choice.
I agreed with 90% of what you had rated. I personly would give Panoptics a 9.5/10 for the 35,27,24,22,and 19. But the 15 only 8.5/10.
Good fun and I enjoyed your post.
