I just looked at the timetable for the Cheshunt/Chingford lines,

and during the repeating sections (all day Saturday and Sunday and
bits on weekdays), there are 8 tph between Liverpool Street and
Hackney Downs, with alternating 1 minute and 14 minute gaps in either
direction at Hackney Downs!

The line map is also crap... it uses a dagger to show that trains to
and from Chingford do not call at London Fields or Cambridge Heath,
instead of just drawing separate lines interchanging at Hackney
Downs, like this

The problem is if you spread out the slow trains more evenly, they will
get in the way of the fast trains to Stansted/Cambridge. Short of
building extra tracks between Liverpool Street and Bethnal Green, I
don't think there is any easy answer to this problem.

Agreed. And even if one wanted to build an extra pair of tracks, there
just isn't any space really.
