In descending order of likelihood (least likely first) the reasons for this evening's performance could be:
1) abducted by aliens and they kept dropping me off at the top of hills
2) I have become a time lord
3) I have a fatal disease that
@RamirezAGC and
@BILL S know about and they were being kind
4)
@RamirezAGC and
@BILL S were just being nice
5) my week in the hills really toned me up
6) my firmware is scuppered
Hope it isn't 3 any of the others (so long as there was no anal probing going on in no 1) is fine by me.
Interestingly (to only me) I have done about 3 firmware upgrades and seem to get a different outcome on each. Tonight is genuinely the first time I have ever seen blue numbers going UP a hill and also the first time I had ever experienced a slingshot. Have since done another firmware upgrade. Ahhh it was fun whilst it lasted.
