Picadilly frequency LHR 4 & 5

What is the pattern and which service is better to take to terminal 3?
From the central area it's as follows :-
Every 10 minutes - Hatton Cross - T123 - T5
Every 10 minutes - Hatton Cross - T4 - T123.
The trains serving T4 pause for 8 minutes at T4 before heading back to
London via the loop and T123. Depending on how pressed for time you
are then it is probably best to take a train for T5 and it will go
direct to T123. If you can tolerate an 8 minute wait at T4 then any
train showing Heathrow as a destination is fine. If you are in a
hurry and catch a train serving T4 then get off at Hatton Cross and
wait for the T5 train that should be following 5 minutes behind.
