Strange use of "arbitrarily" in your question. Generally slower mutating
markers will show less spread away from the founding haplotype marker
values. The 37-67 set of markers have a significantly smaller average
mutation rate as compared to the first 37. Whether FTDNA deliberately
selected those 30 because they were slower or not, I don't know but would
doubt it.

There are many "target" values; a different set for each clade. You are
specifically talking about the R1b1c7 modal values?
