Measuring germanium transistors

[nbabmf]

I'm using RG Keen's method... (collector current - leakage current)/base current in uA

ie. (2550 - 45)/9 = 278. 

The lowest gain I've found so far is 168, and the highest is 404.  The lowest leakage so far as been 33uA and the highest was 82uA.  Only one transistor measured high leakage, in the mA range (destined for AMZ leaky Ge booster?).  So far, so good, right?  Then I realized that the temperature in my garage is somewhere in the 50's.  Given that I am taking all the measurements at this temperature, and therefore they are all in relation to each other with the same parameters, should I be worried about how the transistors will actually perform in a pedal?  My scientific mind says no worries, but I'm worried that my ears might tell me otherwise...

Whoops, my bad.  I'm using the Small Bear method which is loosely based on RG Keen's.

  Thumb and forefinger makes a reliable GE heater for testing.
  Same thing works for biasing in a circuit...get the material to about a low temp, measure, note, raise temp to about a high temp, measure, take notes...put a panel bias knob on with radial dial temperature markings, blue to red or something.
  I had a GEreen Ringer 'heat theremin' thing happening once, it responded with a 12 or so second long sequence of events with just a slow hand wave over the board.

I closed up the garage last night so it would warm up today.  It's probably 10 degrees warmer in here than it was last night.  The same transistor that measured hFE 332 and leakage 52uA last night measured hFE368 and leakage 75uA today.
