AR, similarly, I have never googled anything about wrinkles, but it might be my contributions to the O50's thread that Bill Gates has used to classify me.
RH, if you make an abrupt change of direction at both end of the arm swing when running fast, an inertial device might sometimes count an arm swing as two steps. I think that a crisp arm swing is very helpful at speed so it would probably not be good to try to change your arm action much. However concentrating on relaxed upper body despite a crisp arm swing might help. It is a shame if TomTom does not give reliable cadence estimates

Lead with the hips = lean from the ankle (which I think is what HoD meant). Oh good, MER thread chat is back. Are you all friends again?!  Will watch and never post again though *slinks off* G

HOD, I do not think you should think about ankles.
The main thing is not leaning from the waist or hips. In fact, at foot-fall, the foot must be a little in front of the COG (otherwise your body would rotate forward and downward by an increasing amount at each step resulting is a face plant, unless there is a strong head-wind), so there is no forward lean until after mid-stance. At mid-stance the torso passes over the point of support. After mid-stance, there will automatically be a lean forwards relative to the point of support. Provided you do not bend at the waist, this lean will be from the ankles, which is fine.
HappyG, you are welcome to continue contributing.

Probably been said many times above, so sorry about being lazy and/or repetitive, but...
Keep tall, and don't let your hips fall behind
Pretty well all good, efficient runners have a 'tall' - opposite of slumped - gait. Slower, inefficient and tiring runners often look as if they're about to sit down.

J2R, I agree. ‘Sitting in the bucket’ and leaning forward are very similar faults. Both of these faults weaken the extension of the hips in late stance and thereby minimise the eccentric contraction of hip flexors at lift-off. It is the eccentric contraction of hip flexors that produces a powerful forward recoil of the hips after lift-off, projecting the swing leg forwards efficiently.
