Why We Tell Upside Users to Ignore Last 5 Game Stats Completely
By Matt Downs
If you spend time on the last 5 games panel before you build a slip, this will save you the hour. We teach people at Upside to skip that panel completely. Here's why.
The last 5 games panel is public data
Say a guy's last five strikeout totals are 4, 5, 5, 5 and 13, and the line is sitting at 5.5. You did the work. You found the 6.4 average, you counted how many actually cleared. Fine. Now ask who else has that game log.
Everybody has it. It's public, it's free, and it's been on a few hundred thousand screens since the second those games ended. The people setting that 5.5 have the full game log, the park, the catcher, the umpire, the pitch mix, the injury report and the weather, and they repriced all of it within seconds of the news breaking.
The game log is an input to the line, not a read on it
That 5.5 already has the game log baked into it. The game log is one of the inputs they used to set the number you're about to bet against.
So when you research off last 5, you're re-deriving a price that's already on the screen. It feels like an edge because it takes effort. Effort and edge are two different products, and everybody at the table already did that work.
Why a bigger sample does not fix it
Going out to last 10 doesn't help either. Wider window, same public data, same price. Sample size was never the problem. The problem is that the information is already reflected in the line before you see it.
Where the edge actually is: price disagreement between books
So what's actually left? Books disagree with each other. One book will hang 5.5 on that pitcher while the no-vig consensus across 30+ books says the fair number is closer to 6. That gap has nothing to do with research. Nobody out-read anybody. It's a pricing error, and it's pretty much the only thing on your screen the market hasn't already corrected.
Shopping prices instead of researching players
Strip the vig out of what every book is pricing, sit the real percent odds to hit next to the line, and stop researching players. Start shopping prices. Takes seconds instead of an hour, and it's the part almost nobody else at the table is doing.
The last five games already happened. You're betting on the next one.
Frequently asked questions
Are PrizePicks last 5 game stats useful for picking props?
Not as an edge. The last 5 game log is public and free, and the people setting the line already have it along with park, opponent, pitch mix, injury report and weather. That data is one of the inputs used to set the number, so reading it back off the app re-derives a price that is already on your screen.
Does looking at last 10 games instead of last 5 help?
No. A wider window is still the same public data producing the same price. Sample size is not the problem; the problem is that the information is already reflected in the line before you see it.
If game logs do not give you an edge, what does?
Price disagreement between sportsbooks. One book may hang a line at 5.5 while the no-vig consensus across 30+ books prices fair closer to 6. Nobody out-researched anyone there. That gap is a pricing error, and it is the part of the screen the market has not already corrected.
What is a no-vig fair price?
The price with the sportsbook's built-in margin, the vig, mathematically removed. Comparing a book's posted line against the no-vig consensus of many books shows the real percent odds a pick needs to hit, which is what determines whether a bet is +EV.
