That.
Not only am I chronographing for speed, but also accuracy. I am afraid, with that thing, I would have to do 2x as many loads, the first set for speed, and then a set for accuracy.
I normally load up 5 rounds of different loads, shoot for speed and rough accuracy, then when I get a load that looks good on both speed and accuracy, I will then do a few loads on either side of the one that looks good purely for accuracy.

Ill do a test as soon as I can with factory ammo and my two chronos
Group test w/ and w/o magneto speed, and compare results of the two chrono (magneto vs my chrony beta)
I use the OCW method for load development, load up a set of 3-each of 7 over the span, look for minimum vertical variation over two spacings, expand that range to 9 loads of 3 each, look for vertical spread minimum, pick that one plus one on each side, then load a matrix of 9 with 3 different seating depths around my previous optimum (eg 0.010, 0.020, 0.030 jump), then look for the trend.
Requires approx 80 rounds.
Then I play with neck tension and other stuff to refine.
OWS gets the most stable load, and then the next steps refine for barrel harmonics.
If the 2nd step gives crappy results for vertical spread for barrel harmonics (ie if I get more than 0.5 MOA vertical across the entire range) then ill look at the next best span from the OWS, as there are usually two nodes.
