When to take timing measurements

[Mike Blakey]

When is best to take a timing measurement ?

I'm using a 60-2 wheel, so can time any 6deg pulse to obtain the engine RPM. 
Obviously the nearer to TDC the better, but is the max acceleration (on a 4cyl) not 
at 90deg BTDC ? and so would be a better place to take the measurement ?
