Danirr. What Neil says is by far the best method. Instant pace is unusable in any meaningful way. Simply have a data field showing average pace for the current lap and then set auto lap for whatever distance you prefer. I've experimented with 400m, 500m and 1km and the latter is my preference.
So in a marathon, I will see HR, distance, average pace and pace for current lap. So I can judge my workload, overall progress to target AND I get a reliable estimate of my current speed, but more smoothed off than if I were to be looking at the current pace field. Have been doing this for years. It works.
HS. No, the lump doesn't hurt as such, but I think the movement (flex) in my knee is severely restricted. It would hurt to bend my knee fully. So off to see the surgeon again on Monday. It's a great system here in Belgium that I can get to see someone like that so quickly, with no fancy queue jumping if you can wave cash around.
RR. Driving in Belgium is a bit mad. I mostly notice a complete lack of empathy for any other driver on the road. So you are in the outside lane and want to pull off at the next junction which is just 400m away? And all the lanes are crowded? No problem. Indicating (or not!) seems to establish right of way. Just pull across hard and the others have to look out or brake to avoid you. Ok, it might cause a 5 car pile up, but you just shaved 1.2 seconds off your journey time. You are a winner! I've only been shunted once in 12 years, so I'm doing ok. But as an ex-motorbike rider, you are always expecting every out there to be trying to kill you!
