My meter updates at about 5hz (whereas @AkosLukacs' spikes seem to occur every few seconds), and has been quite good at instantanteous readings so far, but given that no-one else seems to see this I'll tinker some more and report back. FWIW I flashed a second MDBT42V, and that also got the 20uA readings.
