Round 17 recap, and Round 18 tips

In Round 17 ZaphBot did OK, 6/9 - must try harder!
The new bot only managed 5/9 - maybe it's not as good as I hoped :-( 
The only really bad tip was the Carlton game, even Geelong was not a very confident tip

ZaphBot Round 17 results

West Coast by 1, 51% chance
Geelong by 10, 65% chance
Fremantle by 3, 53% chance
Port Adelaide by 31, 80% chance
GWS by 6, 59% chance
Carlton by 36, 80% chance
Western Bulldogs by 8, 57% chance
Brisbane by 9, 59% chance
Collingwood by 39, 80% chance


ZaphBot-New Round 17 results

West Coast by 10, 60%
Geelong by 14, 64%
North by 1, 51%   ** This is the only tip the two bots differ on
Port Adelaide by 39, 87%
GWS by 5, 55%
Carlton by 34, 83%
Western Bulldogs by 5, 55% 
Brisbane by 15, 65%
Collingwood by 34, 82%


Season so far - the new bot is slightly ahead in tips, and has a good lead in Bits: 

                     Tips  Bits  MAE   Correct | Round by Round
ZaphBot-New          100  19.14  23.2   69.4%  | 65466836667787555
ZaphBot               97  14.28  24.3   67.4%  | 84445845766686466
Autobot-PureELO       93   6.16  45.9   64.6%  | 76246654875486447
Autobot-HomeTeam      84   2.42  25.8   58.3%  | 66465913446764562



Here are the tips for Round 18 - you might notice a few 80% tips, that's because I put a hard limit on the maximum tip probability to avoid large penalties for getting it wrong.  Those could probably be 90+ if I left it alone

ZaphBot Round 18 Tips
Richmond by 39, 80% chance Brisbane by 27, 75% chance Collingwood by 1, 52% chance Melbourne by 7, 56% chance Western Bulldogs by 1, 51% chance Hawthorn by 19, 65% chance West Coast by 38, 80% chance StKilda by 22, 75% chance Geelong by 34, 80% chance


For the new bot I've increased that cap to 90%, which may account for why it is doing better in Bits - I'll need to analyse that at the end of the season.

ZaphBot-New Round 18 Tips
Richmond by 49, 90% chance Brisbane by 28, 77% chance Port Adelaide by 2, 53% chance Melbourne by 7, 57% chance Western Bulldogs by 8, 57% chance Hawthorn by 11, 61% chance West Coast by 33 82% chance StKilda by 14, 64% chance Geelong by 26, 75% chance

Round 5

Here we go again.  Absolute shocker of a week last week, I'm now languishing at the bottom of the Squiggle ladder, and I don't even ...
