Is there a standard parachute - streamer conversion formula?

Hi,

Living in the well wooded northeast, I suffer from having recovery areas that are not quite as large as I might like. I frequently will downsize a parachute to bring it down more quickly, and am certainly willing to undertake the occasional fin repair or egg clean-up that may result. It sure beats loosing rockets.

For visibility purposes, I'd like to make more use of streamer recovery of some low and mid power rockets I intend to send on quite high flights from a frozen lake surface (much larger than any grass field) later this winter. Is there a standard way to equate the expected drag from specified streamer dimensions vs. a parachute of a particular diameter?

Thanks!
