I don't think any of us has got it right. Those boats at the extreme West managed it by sacrificing the southerly route to get out into the winds. Now they are tanking along directly to the mark especially Blur.
I have decided to get the hell out of where I was by ignoring VMG and going for speed to the West. I might just get out far enough in time to catch a reasonable breeze past the doldrums before they expand across to the West. I'm making 11.9 knots at the moment.
