interesting views here.....i find it easier to adjust chain with bike on centre stand at the tighest point in the chain if you have one,when finished adjusting take the bike off the centre stand and let bike settle and then give it another quick check.......each to their own of course......there must be a difference in slack between the two methods,parhaps 40mm suits both having 10mm tolerence to suit both methods 
One, is never going to be enough.....
