Subject: Re: [Aus-soaring] Intermediate/short term goals It might depend a bit on the performance of your glider. I fly a Foka 5 I have been very impressed, in a negative way, by the amount of height lost in a large area of sink. Enough to see you on the ground. My very recent endevours have been to find ways to avoid or get out of sink. Has anyone else tried that?

Trying to figure out the below, any thoughts from the floor? The scenario: You've just left a CU, with the cloud direct on track being your target cloud between 3-5km away with an average climb expected, direct is blue and normal sink. 30* to your left/right is a whisp, not one that you'd use to climb in - but one that you could deviate too in order to get reduced sink or a hundred feet of altitude. Do you, go direct through the sinking air, or cover extra track miles to the whisp that you know you're not going to climb in, but get remarkably reduced sink (or even a small gain in height)? For me, I either always just lose out (more often than not) when getting to the next CU, or gain a massive advantage with a 1000' height gain on a competitor in that short cruise. Have you got any rough 'rules of thumb' that you use in order to decide if the short term deviation is worth it or not? ie, how can I get to the next CU by beating the other competitors by second a mile (as G.Moffat would say) if it's possible overall.
