I don't know how potent calypso is as a dry hop, but my estimate would be a 1:1 ratio with Amarillo. Depending on your gravity, I would say 1.5oz of each would be a solid dry hop schedule (3oz total). I think this is a good number as it would be a very very floral dry hop for a smaller IPA, but only the tad weaker side on an DIPA. I let the hops sit for 5-7 days. It can be up to 2 weeks if you dry hop in the keg.
