MDR Question

Hi,

I was 'playing' with MDR and am happy with calculations of around 90 degrees off, but things start to go awry with bigger numbers.

For example, let's say the wind is 040/30 and I want to divert from a heading of 125 degrees to a track of 185 degrees. TAS is 95kts and I make the Max Drift 18 degrees.

My MDR calcs tell me that the wind is 145 degrees (185-040) and therefore I should apply max drift, but I know that this is incorrect.

What am I doing wrong?
