Mike's distance tactics

@Reto. Yes- thermalling can be aggressive tactics, but in my mind not necessarily risky.

It comes down to the way the thermal is drifting, the wind direction compared to course layout and your judgement of height gain compared to the position of other aircraft on the course.

It is nice to contact lift at an upwind distance outside the course that allows the full extent of working time to be used. During this circling period, the thermal drifts onto the course. You can then safely start with 4 minutes to go at high pace, with a substantial height advantage, and tactical advantage knowing that the thermal is in course, and extends below you and closer to base b at lower heights, so as you burn height chasing high pace, the lift remains with you. This is how to get 40 laps

Circling lift to follow it further away from the course is risky... This is how you get 20 laps when every one else gets 25-30

It's difficult for me to visualize Mikes 32 lap run. Was the course laid out in a downwinnd direction?

How many distance laps do you guys do in a 10 minute task?

Conditions were light and wind direction was dictated by the thermals. That round the thermal was on the course. Mike launched downwind onto the course and thermaled up before getting off and back on course. Everyone else elelected to launch into the wind off course. They got on course and stroked laps while in the lift. Mike's strategy worked in this case because the lift stayed on course and he was able to work it before his working time started and during his working time. If there was any prevailing wind, this strategy may not have worked. Mike recognized that things were moving slowly and took advantage.

How do you set up your course relative to the winch line guys?

We have our course in to the wind and the winches in to the wind. We don't really have room for winches going more than one way. Although we usually have some wind any way.

I'm just trying to understand the situation. If you launched down wind in our set up you would be way off base A and off the course.

We were able to launch in two directions.

The wind direction during the contest? When there was some wind it had a direction. It always changed through the day.
