Round 17 Tips

Here are the tips from the two bots this week, Round 17 2020.  They differ by only 1 tip, although there are a lot of close games being predicted.

ZaphBot:

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

The New Bot:

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%

The New Bot (needs a name) uses a different method, including some questionable mathematics that just happens to cancel out and end up tipping OK.
I'm not sure I'd be ready to switch to the new bot yet - I have another alternative ZaphBot that is the same algorithm but trained to get a better Bits score rather than the current Tips score, it does much worse on margins but ends up tipping a similar number of winners.   This new bot does better than that, and is also trained to improve it's Bits score even at the expense of getting tips wrong.
