Are the proposals really going to increase Northern Line frequency by
25%?

That's what they say:

"Following the PPP Northern line upgrade, the line will operate 30tph
on the southern Morden to Kennington section, but the branches through
central London will be operating at only 22-25tph and will remain
crowded. The limit on capacity is the need to inter-work services to
different destinations via different branches. It is possible to
achieve higher frequencies and capacity using the existing
infrastructure if junction capacity limitations can be overcome.

"A segregation of services would deliver simpler service patterns on
the line. This will allow more trains to be run through both the West
End and City branches - enabling 30tph services on the central London
branches. This will provide roughly 25 per cent extra capacity and
crowding relief on these busy sections. With the core infrastructure
being capable of supporting these service patterns, the main
requirements are some additional trains (and stabling) and station
capacity improvements at Camden Town."
