From the judges guide:

d) In all manoeuvres which have more than one continuous roll, the continuous rolls must have the same
roll-rate. In all manoeuvres which have more than one part-roll, the part-rolls must have the same roll
rate. Lines between consecutive part-rolls must be short and of equal length. Between consecutive
continuous rolls or part-rolls in opposite direction there must be no line. Where there are continuous
rolls and part-rolls within one manoeuvre, the roll-rate for the part- rolls does not necessarily have to
be the same as the roll-rate for the continuous rolls.
