Why 4 years between indyrefs is normal

General elections (GEs) for the UK have varied from

8 months to 5 years apart – but were often 4 years apart.

GEs for Scotland are 4 years apart.

Time between IndyRef1 and IndyRef2: at least 4 years.

How do GEs and Refs compare?

A GE is a vote on a basket of refs you’d vote Yes to.

A Ref is thus just a GE with one ref in the basket.

So what's the problem?                                    

4 years between one-ref GEs is perfectly normal!
