6 ft. flyrod guide size & spacing

[JeffS]

I am planning to build a 6 ft. 4 weight fly rod.
My question relates to guide spacing and size, I intend upon using single foot guides. The guide spacing chart from Stockard and St. Croix for a 6 ft. fly rod indicates a spacing of:
4in., 8.5in., 13.5in., 19in., 25in., 32in., 40in, 50in. using the following sizes 2, 2, 2, 3, 3, 4, 4, & 10 stripping.
I was under the impression that the general rule of thumb was 1 guide per foot of rod which if true would make this excessive.
Any suggestions would be greatly appreciated.
