Statistically, I was looking at the number of GSDs and wolves that were used as foundation stock for our breed. 48 GSDs and 5 wolves. 5 is not 30% of 48.

presupposed here is 5/48 = 10,42 %, which is indeed not 30%... . This may be again “the American way” but it’s a wrong assumption, at least regarding the way how the (mathematical) wolf blood percentage is calculated in our breed with for example the moreover fantastic statistic tool, Elf made available. This mathematical wolf blood percentage doesn’t say a lot, but that's already discussed in this and various other topics. It’s just math's not genetics, as we simply like figures....
Back to the evolution of this mathematical wolf blood percentages of our contemporary Csv’s you are refering to in the quote: Not 5 wolves are used, but 4, which mated 6 times. 4 of these matings with gsd’s and 2 matings (Sarik) with F3 and F4/5. The first generation of these 6 wolf matings were crossed with GSD’s and with other F1’s-F4’s and went on in the breed. So several of the F1’s-F4’s were also intercrossed, f.e. F1 XF4, F2 X F3 etc.
The total number of GSD’s used in the matings is 43 (maybe I could have overlooked one), not 48. Most of them mated with F1’s-F4’s. The reason you find more than 43 (or44?) GSD’s in our pedigree is that in some occasions also one (or two) of the parents of the used GSD’s are included in the database, for example Nancy von Steinstücken (__NO__) and Ohle vom Rundeck (__NO__) are included, but they weren’t used in the breed theirselves, their son Bojar vom Schotterhof (__NO__) was used. Or Tula Irka (__NO__) which is included in the pedigree database, but wasn’t used herself, her daughter Centa Irka (__NO__) was.
The 43 used GSD’s mated 50 times. 22 of these GSD matings didn’t go on in our breed. The 6 wolf matings did. See also this topic. So from this point of view nowadays our wolfdogs are in base descent of 28 GSD matings and 6 wolfmatings (26 individual GSD’s and 4 individual wolves), not to mention the intercrosses between the F1’s-F4’s of which specifically one was used excessively often: Rep z Pohranièní strá¾e (F3) . He had a (mathematical) wolf blood percentage of 42,19%, which again doesn’t say a lot. This all declares why nowadays our Csv’s have a mathematical wolf blood percentage of about 27% (with some outliers up and a number below) to which is often refered to.
@Rona: beautiful picture! I think it's a very nice looking wolfish Csv
