polars

For big boats there often exist polars where I can compare wind speed, course direction and the resulting optimum boat speed.
- Does such polars exist for the laser too?
- Do they make sense in respect to the different planing conditions?

Estimates have been made but not any accuracy worthy of useful analysis. I have tried searching in vain for a decent one but havent found one yet...
