Why do these two resistor networks measure differently?
200kohm resistor , with a 5% tolerance could read anything between

200,000 - (200,000*0.05)
and
200,000 + (200,000*0.05)

so 190k to 210k

Looks like your simulator is also simulating a random tolerance within the above range.

for the 100k it goes from

95k to 105k
