I never let the penguin swing all the way round and release on either the top of the swing at 10.00 clock position or at 1.00 clock position this causes the penguin to bounce off the seal and go higher if you aim for the 4th seal on the left hand side he has an auto reaction to pass the seal up thats at the 25,000-26,000 ft if you do it sooner he runs out of steam.
Good luck my average is 138,000 as I still have a tendancy to drop the penguin after a high score. but you should get at least 2x 30,000 throws.
