It's really pretty, and may well be a world record for Phalaenopsis, but no way it's a record for all orchids.
Brendan you need to get out more - go to an orchid show near you when you get the chance. You'll see orchids (other genera) with hundreds and hundreds of flowers on them.
I took this picture years ago on a trip to a grower in Apopka FL. That's our friend Jim standing beside this enormous plant. The grower used to take it to orchid shows, hoisting it into the bed of a pickup truck with a power winch. It finally got too big even to do that.
