#Superugby predictions week 6: is quality of opposition relevant?

Our predictions were slightly below-par last weekend, getting 4 of weekend’s 7 games correct. Unfortunately two of our outside bets, the Waratahs and Stormers, ended up on the losing side.

This weekend looks like an interesting bunch of games: the Crusaders and Bulls are favoured to win, by quite a margin and based on any of our criteria, but the rest of the games look much closer. Picking the Sharks to beat the Chiefs is a result of the Sharks hammering the Cheetahs in their last outing, and a bit of South African bias in the Superbru forecasts. Incidentally, we experimented a bit with weighting a team’s performance in the last game by the quality of the opposition faced, as measured by their current log standing. None of the predicted winners of the weekend’s games changed, so we’ve left things as is for now.

As always, we’d like to hear your thoughts on the model?

 

SuperRugby Round 3 based on prediction model

Last weekend’s predictions fared a lot better than Round 1. From 1/7 we’ve gone to 4/7. That means by extrapolation this weekend we should get 100%…

Here’s how last weekend’s games happened:

Here are the Rugby Scientists’ prediction, triangulated from predictions made from past seasons points tallies, previous game analyses, and adjusted Superbru forecasts. The forecasts make it look like we’re in for a weekend of close games, although for three of the games the margin, form, and Superbru predictions coincide: Hurricanes to beat the Force, Sharks to beat the Bulls, and Stormers to beat the Lions, all away.
