You are right, the Verdant pitch rate seems to be similar to their other ale yeasts. Personally, I would be comfortable pitching 1 sachet in 5 gallons of 1.060 wort. That's me, YMMV.
The Koln seems to be an outlier. 28.4 grams of dry yeast for the same 5 gallons of 1.060 wort, doesn't pass the reasonability test, for their yeast. Agree with Denny, they may have a typo.
