the 180 is in straight line and on grass , if you added 2.1 for the last 20 ( I tend to die at the back end of 200) and factor in the bend + 0.2 20.7 + 2.3 = 23.0 for 200 on grass-
I would be around 22.8 e shape for the 200; my pbs for the last few years is 22.2.
I am injury free at the moment- so I should be dipping inside 22s this season.
The plan is to dip inside 50s for the 400, 22s for the 200 and 11s for 100m.
