ok i'll try it tomorrow, bit late to do it now, or i'll fuck all the neighbours off.

What would it prove though? that it was just a false reading? and that its still number 4 that is the issue and non of the other.

I did do number 1 twice as it was suprisingly high, but both result came out the same, infact the second attempt was slightly higher, i presume due to heat.

I did, 4,1,2,3, 1,2,3,4. All reading were pretty much the same as the first
