Abstract
We clarify the relationship between the two most standard measurements of the order of contact of q-dimensional complex varieties with a real hypersurface, the Catlin and D'Angelo -types, by showing that the former equals the generic value of the normalized order of contact measured along curves whose infimum is by definition the D'Angelo -type.
