Some other ideas on how much speed bar to apply from the FlyMaster website as Dave Cantrell mentioned at the last club meeting…
Airspeed to get to the next thermal at highest altitude..
• Know what your glide is in still calm air
• If your glide ratio is now lower than glide in still air, apply bar
• Amount of bar to push to a function of current glide:
Assume GR 8 in calm air.
Current GR 6. Amount of Bar to push:
Divide up speed bar range into quarters:
Amount of bar to push is 2/4: i.e half bar

This week's Tuesday Tip comes from a 'speedbar masterclass' in the latest issue of Cross Country magazine. It's from Adrian Thomas, who is currently competing at the European Paragliding Championships in St Andre, France.
Packing Your Glider <http://pr.ak.vresp.com/510ad7123/www.xcmag.com/newsletters/tuesday-ti...>
There isn’t a hard and fast rule for when to use the speedbar, but you will find that the more experienced pilots rarely glide without using the bar. If you are aiming at maximising your average cross country speed, then as a rule of thumb if the thermals are giving you an average climb rate of 3m/s (ie any reasonable day), and there is any sink or headwind around then the correct theoretical speed-to-fly is likely to be full speed, even on an EN B. There are some outstanding pilots around who use the speedbar like that – flying with two modes – full-bar or thermalling.
Personally, I generally go to quarter-bar as I leave the thermal and then move up from there, rarely gliding below half-bar, often going full speed. But for me speedbar isn’t an on-off thing, I use it very actively to control pitch, pushing hard as the glider pitches back, and coming off the bar completely when the glider dives forwards through rough air.
One tip: the load on the legs is very much less if you push the bar with the ball of your foot rather than having it sit in the notch of the heel. You can do fine pitch-control with the calf muscles, which are fast, strong and have great endurance.
