This simply tells you what the tester is capable of.In all my experience all these years told me you can't get a consistent relative reading on small high mu triodes because it varies from manufacturer to manufacturer.
I have some old Telefunken 12AX7s that test 15% of what many new 12AX7s test and they work fine when you put them in the circuit.
If you're buying this unit to sell tubes with,I get why you might want this tester for readings..If it's for personal use or even sales for that matter,you want a tester you use for noise and microphonics.How much do they want for this tester/matcher?
