Pico power consumption down to 0.02mA

So, my next report (try 2) for all three tests as above for three-four minutes each; using multimeter UT50B made by UNI-T:

// test 1.2: ~61uA
digitalRead([B15,B14,B13,B10,B1,A7,A6,A5,A4,A3,A2,A1,A0,A10,B9,B8,A8,B7,B6,B5,B4,B3]);
setInterval('digitalPulse(LED1,1,10)',60000); // actual repeat time is about 50 seconds
setDeepSleep(1);

// test 2.2: ~48uA
digitalRead([B15,B14,B13,B10,B1,A7,A6,A5,A4,A3,A2,A1,A0,A10,B9,B8,A8,B7,B6,B5,B4,B3]);
setSleepIndicator(LED1);
setInterval(function(){
}, 60000); // actual repeat time is about 50 seconds
setDeepSleep(1);

// test 3.2: ~59uA
digitalRead([B15,B14,B13,B10,B1,A7,A6,A5,A4,A3,A2,A1,A0,A10,B9,B8,A8,B7,B6,B5,B4,B3]);
setInterval(function() {
  digitalWrite(LED1, 1);
  setTimeout(function () {
    digitalWrite(LED1, 0);
  }, 20);
}, 60000); // actual repeat time is about 50 seconds
setDeepSleep(1);

Wow, power consumption has drop almost 10 times! Anyway, I did not reach result mentioned above my notes.

Any comments/suggestions are welcome!

NB: here is open question, that is about power consumption in case of all connected circuits to PICO, like InAir9B, PIR sensor and 4 pcs DS18B20...
