How Strava mangles data after upload is a mystery.. I see the average speed change and when uploading from my GPS I've seen the ave HR change too.
Usually its issues that arise when using autopause etc on Garmins. I think the average speed the Strava app shows is showing a rolling average and not the average speed over the whole ride. My commute home has a fairly fast, last couple of km's with a single traffic light just before turning off for home. If I stop for the light the average speed shown when I stop the ride is low, if I go through it on green it's higher and much closer to the true ride average.
I apparently got a 10th place on a descent on the weekend, but then the leader board showed me as 11th I couldn't believe it.
As Rob says, does it really matter? I did used his time on the above segment to pace myself with live segments. Dangerous stuff, I will aim to be less than 6mins slower around Richmond Park!

It doesn't matter, I'm just curious to why it works like that , as it is interesting to gauge average speeds doing the same set route everyday, I'm lucky in that my commute doesn't have any traffic lights or things to stop for over 10 miles , bar 1 roundabout, so you can push on more.
You can't turn autopause off on the IPhone, I guess I should upgrade to a garmin/etc, but I would only keep it in my pocket anyway as I don't want distractions on the handlebar , so I cant be bothered with something else to lose /break/charge/deal with .

Something a little screwy going on at the moment with the Android app. It had me averaging 7900km/hr over 2600km on the way in this morning, and 9800km/hr over the 4600km commute home. Oddly enough, the route was correct on the map.
Exporting the ride as a GPX and re-uploading it fixed it. Little miffed that Mach 8 still wasn't quick enough for a KOM though

Ah yes but that stop allows you time to recover so your pace after will be higher than it would be if you hadn't stopped 
WooHoo! 
I went onto Strava this morning to edit some details (parts swap on the bike, mainly) but dipped into my own details at the same time.
So I ended up having to edit my weight! Feck knows if it'll make the estimated power and calorie consumption results more accurate or not, but it certainly made me feel good knocking 10 lb off my profile weight.
My bodyfat analysis is far better too, down from a high of 25.6% last year (slightly better than "average") to 21.3% currently (between "Good" and "Excellent").
BMI still has me classed as 'Overweight' though. Wants me to lose another 10 lb, but I'm hoping it's true that muscle weighs more than fat. All data from the same calibrated machine, so should be fairly accurate.
Oct 2013 - 78.9kg, BMI of 28.3, 24.0% bodyfat - getting back into regular cycling after some issues with depression
Apr 2014 - 79.2kg, BMI of 28.7, 25.6% bodyfat - after two months of almost complete inactivity following a broken scapula
Sep 2015 - 74.2kg, BMI of 26.6, 21.3% bodyfat - 3,660+ miles so far this year, having bought myself a tidy new road bike
I think I'd like to get to, or below, 70kg and stay there. That'd make me pretty darned happy and ought to make life easier (and quicker?) getting myself up hills.
Why post this guff here? Well I suppose it'd be better in the health and fitness forums, but it's using Strava that encourages/inspires me to get out and ride more, which is what has helped with losing 5kg (4.4kg of that being fat) since last April. I think I shall get myself weighed/measured more often now, to keep a closer eye on my 'progress'.
ETA: Sorry for the mix of metric/imperial units, but Strava is set to miles/pounds whereas my brain handles miles/kilograms better. Which begs the question "Why doesn't Strava allow me to choose imperial units for distance and metric for weight, separately?"

Re body fat, how are you getting the measurement? Home scales etc. are notoriously inaccurate, the only proper ways are through a caliper test or use of a BodPod. I tend to just base it on how my clothes fit and whether I'm happy with my body shape overall.
Technically, muscle doesn't weigh more than fat - 1lb of muscle weighs the same as 1lb of fat - both are 1lb. But muscle is more dense so 1lb of muscle tissue takes up much less room. Muscle also requires a blood supply and having more of it actively burns calories. So, if you lose fat and build muscle, you'll burn more even at rest.

What's heavier, a ton of feathers or a ton of lead......? loudlashadjuster said:

I was working out what weight would put be at 6ft 1 on the lower bound for BMI (18), it was a staggering 62kg. Well I am down from 92kg 2.5 years ago to 78kg now, 4 kg own the last 6 weeks through 1600cal a day diet.
People at work are asking if I am unwell!
3-5kg to go (target 73-75kg), which should make Tenerife easier I.e, faster than 81kg last December! November roll on!

Weight and bodyfat measurement are from a machine in my local Boots. The bodyfat thing? Pay an extra 20p and grip the handles when instructed. Presumably some form of electrical resistance measurement?Re body fat, how are you getting the measurement?

I'm not on a mission to lose weight, so the absolute accuracy of the system is of no great concern. I presume that by using the same machine every time, I'll get an accurate trend for loss/gain.
As for the x weighs more than y thing? Yeah, I know about mass/weight/density, but in my defense it was a direct quote from the pharmacist who offered help when I was stood studying my little printout.
I was just happy to a) weigh less, and b) have reduced my bodyfat %, without really paying any attention to diet (I'm a KFC once a week man, and never leave food on a plate). All I've done is ride my bike, and always simply because riding a bike is a 'happy place' for me, never because I need to do it to lose pounds/kilos. Strava challenges have been a spur to go out some days when I might not have otherwise bothered, but even a two-hour drenching a week or so ago left me with a smile on my face (once I'd showered and warmed up, of course
). Like I said, I'm not on a weight loss programme, or diet of any kind. I guess that if I was willing to suffer for it, I could get back to my teenage ABA Junior Featherweight upper limit of 57kg, but back then I was a recruit in the army, and these days I lack the structure to discipline myself for that kind of dietry and gymnasium hell. I like pork pies and cake too much...
