Why is it if you board certain services from Cockfosters that you may be asked to change for the Northfields service on the opposite side of the platform which leaves before the through service instead of the latter?

Might be something to do with a crew changeover i.e. the driver of your train will do (e.g. Heathrow) - Cockfosters, then Cockfosters - Arnos Grove then have a break and another driver will take over, which could have a few minutes waiting time added.

It would be because the, in this case, Northfields service is timetabled to depart before the train you are on from Cockfosters.
Note that with the current timetable it isn't just Northfields trains that reverse at Arnos Grove but Heathrow and Uxvridge/Raybers services.
During times of disruption there may be more trains reversing at Arnos Grove then there is timetabled.
Generally trains run in a specific timetabled order and it's the timetable that guides as to which train would depart first in the example you have described in the original post.

Does that mean that there are offpeak trains from Heathrow, Rayners, and Uxbridge that don't run all the way to Cockfosters? |

I've always been led to believe that off-peak Arnos Grove - Northfields services run every 10 min, totaling 6 tph - or has the WTT changed?

Does that mean that there are offpeak trains from Heathrow, Rayners, and Cockfosters that don't run all the way to Cockfosters? Yes this is correct. However, in the current timetable there is a short period where about 70% of trains that terminating at Arnos Grove start at Northfields between 1100 and 1600. Between 1200 and 1500 the figure rises to 8 out of 9. Before and during the morning peak most come from Heathrow Terminal 5 and during and after the evening peak most come from Terminal 4. When departing from Arnos Grove most go to Rayners Lane, Northfields and Terminal 4 during the morning peak; to Northfields between the peaks until about 1500 and then Terminal 5 during and after the peak with a few Uxbridge and Rayners Lane services becoming the majority later in the day. |

How often do trains terminate at Oakwood?

I don't have an exact figure, but from general observation it tends to be a post-10pm thing where, say, 1 in 4 trains will terminate at Oakwood rather than Cockfosters. On the other hand, Wood Green terminators (someone is bound to ask!) will occur during peak periods where there are too many trains for Cockfosters and Arnos Grove to handle.

Wood Green is often used to reverse late running Arnos Grove trains. It used to be a regular off peak reversing point many years ago (there was a Wood Green - Barons Court service) but it hasn't been so for a long time now.

The trains that terminate at Oakwood are going to Depot after the morning peak they remain in Cockfosters Depot until need for the afternoon service which come out via Oakwood. |

In the evening every 1 in 3 trains start to terminate at Oakwood from just after 2300; this equates to about 1 every 10 minutes.
In the morning 4 trains stable from Oakwood roughly between 10 and 12 and as stated previously in the thread these come out again for the evening peak between roughly 16 and 17.

Surely this thread should be titled "Arnos Grove, starting train leaves first" ?

During late 70s and the 1980s crew/driver changeovers also took place at Wood Green. There was a train crew office on the northbound platform.

Occasionally I have caught a train a reversing at Oakwood, normally mid-morning...is this a regular thing? |

The way to tell which train is leaving first, aside from looking at the signals, is to look at the DMI boards on both platforms, whichever one is showing a destination is the first train to leave.
Usually the drivers will make an announcement anyway (we hope)
