I did it my wonky sums method.

R9 = (R8 measured+R9 measured+R10 measured)/2 = 1.0695meg.

R8 = ((R9 measured+R10 measured)2) - (R8 measured-R9 measured)
= 2.270meg.

R10 = ((R8 + R9)R10 measured)/(R8+R9)-R10 measured = 0.5107meg.

1.0695m + 2.2270m = 3.3395m.....3.3395m in parallel with 0.5107m = 0.4429m

Sort of a one off near enough
