The following chart shows the individually measured capacitors, and then the parallel combination of all of them:

And you can see that a single 10uF capacitor performs best up to when the 10nF capacitor kicks in. Which is why you shouldn’t use decade capacitors.

Yes, it was a bit surprising just how much range that 10 µF MLCC has.

Which is effectively what Ott recommends: put as many of the largest value capacitor you can get in the smallest package as you can.
