It’s accuracy will improve significantly as the season progresses and it consumes more information.

I also plan to update the predictions and share the tool each week. I’ll be using it over the next two days to get my team ready for the season opener this Friday. There will be information that the model cannot capture, or clear biases in the data - I always want to create tools that allow me to recognise and correct these issues.ĭownload it here and have a play. My principle is to use data to augment, not replace, human expertise.

produce more of a given crop activity, and the model is solved using the simplex LP method. I’ve also added functionality to allow you to make manual adjustments. For climate predictions for the year 2050, we refer to the. I’ve built a tool in Excel to do exactly this. We can use an algorithm to find the top scoring combination of players almost instantly. There is a much better way: optimisation. I can use trial and error, looking at the predicted total scores for different combinations of players, but unless I’ve got a few million years to spare then I’m not going to find the highest scoring team. All we need to do is pick the team with the highest predicted score over, say, the first 10 weeks. Selecting an opening team using this principle is straightforward, assuming that we think our forecast model is good. The FPL season is very long, so if I consistently make decisions that maximise expectation then the luck is likely to even itself out. My actual points ended up on the low end of the scale in those thousands of seasons, but so long as I was right about my expected points then I’m happy. Now, I could be unlucky and start the season badly.

I want to pick the team that scores highest on average across all those seasons. Let’s be clear about what expected points means.Ī trick I often use is to imagine thousands of simulations of the season, each with slightly different outcomes. (For those who are interested) a step-by-step guide to team optimisation in Microsoft Excel using the Solver Add-inįPL is all about points - I want to pick the combination of players that delivers the most expected points.A tool to select optimal teams and interrogate player projections.My general philosophy of decision making to maximise expectation.

In this part I discuss how to use these projections in practice. In Part 1 I went through building a model to project player scores for the upcoming season.
