Unlike the JLE, many of the southbound services will be half-hourly. I think
one of them will even be hourly IIRC.

Outside of late nights and early mornings the frequency of FCC TL
off-peak services through STP is generally 8tph; during the morning peak
hour 15 southbound trains call at STP.

Perhaps you are talking about the services to each destination, but even
then services to/from Brighton or the Wimbledon/Sutton loop run at an
off-peak frequency of 4tph each during weekdays (weekend frequencies
during the weekend - particularly during Sunday, are admittedly lower).
