I agree with Your statement but then, what of the depicted level flight from SEY 6.5 to SEY 4.4?
Is it not strange for the 1760ft OCH to appear lower than the supposedly 1120ft minima at SEY 4.5?
It doesn't actually - the shaded portions (very faint) represent the
OCA. The profile depiction is diabolical, and doesn't really represent anything - I suspect they didn't really know what to do. The JEPP depiction is better, but follows the dive and drive principle.
A 5% descent gradient (300ft/NM) to 1120ft does not work as you will be 1720 ft at D6.5 - IMHO would have been better to publish a 5.2% gradient (3 deg/320ft/NM)) profile back from 1120ft at D4.5 (and publish the descent angle) - 1760ft @ D6.5 and 2880ft @ D10.0 - with a distance/procedure advisory altitude table to match, or the procedure altitudes at the relevant distances, or both!
Be careful out there....
