Default Atrial flutter: Ratio of sawtooth pattern

Hi, can someone clarify if v consider the sawtooth wave (embedded in QRS) when discerning the ratio..

For example, the atrial flutter sawtooth wave ratio in FA2015 page 284 should be 5:1 instead of 4:1??

Thx a lot Shidox! I also think it should be 5:1 in FA 2015.
