That isn't correct.
The 5/32" flame channel had a 27 fps total spread.
If one tosses the 1929 fps shot on a cold clean barrel, the 1/8" flame channel had a 16 fps total spread.
The 1/8" flame channel had the least spread when comparing fouled barrel, and it also had the highest velocity.
More testing is required.
