My suggestion, possibly unhelpful but offered in earnest, would be to learn to read slope with your feet and forget your eyes. I am serious about this. Mackenzie greens are murder on eye reading.
Then go back to CPC and see what feet tell you.
If pedi-reading proves too difficult then just let me know next time you head out there and I'll be happy to tag along. I generally am on call for this sort if thing Mondays through Sundays but I require at least 8 hours advance notice owing to the vagaries of transcontinental travel.
Helpfully,
