Since V2 is also ground, when removing R1, you will have 5V drop across the thermister all the time...

Is V2 also connected to ground? This is what I see from your circuit Vdrop = Thermistor/(R1+Thermistor)*5V You will have the maximum Vdrop when R1=0, but it is...

... Correct, V2 is ground. ... Ah, ok. So I was wrong with (T1/R1) = (Vthermistor_drop/Vtotal) and it should actually be: (T1/(T1+R1)) =...
