Comments
1. Traditional Output is based on results of analysis of the stroke rate and boat rigging, which were conducted during major world regattas: World Championship and Olympic Games. These are the average values currently used by elite rowers(RBN 2006/11).
2. Innovative Output is based on results of biomechanical modelling. The algorithm is the following:
    - Inboard is based on the optimal rowing angles (RBN 2009/05) and a function of the arc length on the rower's height.
    - You can input your desired racing rate. The Oar Length is based on an assumption that average handle speed should be constant in this boat type. Therefore, the lower racing rate -> the longer drive time -> the slower average handle speed -> the longer outboard and oar length to match the same blade speed / boat speed, and vice versa. It is possible to use reversed logic: the obtained Outboard/Oar Length will not allow you to increase the Racing Stroke Rate above given value at given boat speed /rower's power.
3. Target Angle Mode specifies how the total rowing angle is set:
1. "Standard" - "Gold standards" for different rower's categories;
2. "Custom" - You can input the Target angle in the box below.
4. All constrains are ignored, if no solution found. Try with only one constrain first, then add others.
5. You can use this option to findout what stroke rate corresponds to the given combination of rigging and boat speed.
