That is consistent with the equation for springs in series (1/k = Sum(1/k1 + 1/k2 ....)), which you can look up anyplace.

HIS MATH shows springs with a deflection of one inch per 100 lbs..
HIS MATH figures that at .1 inch deflection.
The total load ...100 lbs... is spread between the 10 coils ..thus causing each to bend .1 inch... his example set the deflection rate of one inch per coil per 100 lbs load..
Don't give up so fast on your initial judgment..
