Thanks everybody's help to make the contest so fruitful.
F Fai, it's OK. After a quick fix to the plane, I can still continue with the contest with faster lap time. No problem! Can justify with the smile on my face. Yeah!
Have to thank Ah Wai for powerful launch. Much Thks!

Thanks everybody for helping to make this contest a success!

By the way, dear fellow pilots and photographers, since I was too busy involved in the race and didn't take many photos, would you please send me some of your best photos so that I can post them in the report?
I would particularly need the group photo in full resolution. Many thanks

In addition to the "fastest time", I think there are more meanings behind the data:

Below is the standard deviation of the flying time in HKF3F open day 2.

Cheung Wan Kin 1.629301998
Cheng Chung Ming 1.050789386

Stanley Chan 5.892409666
Wing Wong 5.779246635
K.Y. Mak 5.611187486
Rico Lee 6.901717178
Au Chi Fai 13.56330466
Lee Joon 5.205333002
Angus Lee 5.702294129
Choi Wing Pong 5.72360245
Y.C. Lui 5.689367276
Chan Kwok Wai 9.783763335
Chang Ki Sung 14.42185003
Johnson Yeung 3.47287105

So Kwok Ying 11.21678021
Lo Kwok Wah 7.193487796
Henry Chan 4.393825213

Ha Ha you see I've got the most stable performance, which means I do not depend on LUCK!! Watch out guys, if I fly fast next time then I will continue to lead the race . 8) . . :lol: :lol: . :o .. 8) . :) dreaming :lol: . :roll: . :P . :lol: . :D :D . .

Standard deviation alone is not a good measure, you need to take into consideration the Mean also.

With a low mean and small standard deviation that means consistently to perform poor

With an average mean and a large standard deviation that means sometimes he can do much better such as the case of Ko Lo Wai

What we aim for is higher mean, smaller standard deviation

Just discovered that I had taken a movie for a false F3F run by Fat Fai during the HK F3F Open. This is due to judge error not his fault.
