Yes, running it against the clock, using a PACT timer or something similar, would be the ultimate test. FWIW as well as hunting I have run against the clock a good number of times in competition, and it is a good truth-teller. The additional bit of pressure of competition and a timer also tends to find out other issues with technique, rifle reliability and your performance under stress. So too of course does a critter galloping at you ;-)
FWIW here's a bit of benchmarking. The Bloke got down to a bit over 6 seconds for 10 rounds, using a much modded Lee Enfield. These do lend themselves to fast operation, and you'll see how other actions fared in comparison:
You might also find this one interesting, where he talks about the technique. There's also a consideration of the "palming" technique from about 9:25. While he's mostly using the Lee Enfield as an example, he does also look at the Tikka. FWIW I use the ball and socket technique for all bolt actions, and anything which puts the bolt knob down near enough to the trigger also lends itself to the middle finger tripping technique.
