As you already stated, this can be a hotly debated topic. And the hydraulic lifter will still collapse some when full of oil, it uses that compression to get oil up to the rocker. If your test results show your even close to the pattern your after, go with it. Your static "test" may or may not be reality with dynamic operation anyway.

And it is good to see you here, thanks for the question! When you've a chance maybe share a pic of the project.
