Start with a clean sheet
Open a new file, name it “Greyhound Tracker.” Think of it as your betting cockpit, the cockpit where you keep a mental map of every race, every stake, every outcome. The first row—headers—is the backbone. Date, Track, Race Number, Dog Name, Odds, Stake, Win/Loss, Payout, Profit. If you’re using Google Sheets, set the first column to Date and format it as “dd‑mm‑yy” for quick filtering later.
Automate odds and payouts with formulas
Formula time! In the Odds column, pull raw odds from your betting platform using a manual copy‑paste or, if you’re a wizard, a custom script. In the Payout cell, write =IF(G2="Win", B2*C2, 0) – where B2 is Stake, C2 is Odds. The Profit is simply Payout minus Stake. The magic: as soon as you record a win, the sheet spits out your net gain instantly. If you’re on Google Sheets, consider the QUERY function to pull race results from an external source; it’s a game‑changer, but keep it simple at first.
Build a rolling summary
At the bottom, a rolling total: =SUM(H2:H1000) for Payout, =SUM(I2:I1000) for Profit. Then a win‑rate percentage: =COUNTIF(G2:G1000,"Win")/COUNTA(G2:G1000). Keep the numbers fresh; they’re your sanity meter.
Color‑code to see the pulse
Conditional formatting is your visual ally. Highlight any Win with a green fill, Losses in red. A quick glance tells you whether you’re in a losing streak or riding a winning wave.
Track by track
Insert a separate sheet for each track if you bet across multiple venues. Use the same column headers for consistency. Then, use a master sheet that pulls data via =IMPORTRANGE() or =VLOOKUP() to see your overall performance. It’s like having a dashboard in a single pane.
Dynamic bet sizing
Apply a simple Kelly criterion formula to decide stake size: =(B2*(C2-1)-1)/C2 where B2 is your bankroll percentage. The output guides how much to wager each time. Keep the result rounded to the nearest dollar.
Log metadata for context
Don’t forget the “Dog Name” and “Track” columns—they’re essential for pattern recognition. If you notice a particular dog consistently outperforms others on a certain track, the data will reveal it.
Use filters for deep dives
Click the filter icon on the header row and isolate races where odds were under 2:1, or where you lost. Analyzing these subsets surfaces biases and tells you where your predictions need sharpening.
Export to PDF for sharing
Google Sheets lets you export a range to PDF. That way, you can send a snapshot of your recent performance to a friend or a betting community.
Keep it real
Staying disciplined is tougher than keeping a spreadsheet neat. Stick to the sheet, update after each race, and avoid the temptation to guess later.
