Analysis a di sector dem
Physical defect affec pocket weh deh side by side all togedda, suh test arc a di wheel, nuh jus single numba.

Group di 37 pocket inna sector weh run side by side, an compare di hit yuh see wid wah yuh expec inna each sector. A real bias usually show up as one or two sector next to one anodda weh run hot cross independent sample.

Work out z = (observed − expected)/σ fi each sector. A sector ova +2 worth a second look; ova +3, inna two independent sample, it interestin.
Wah mek sector
Single-pocket test have 37 chance fi throw a false positive, an a weak signal inna each one. Sector test have six chance an a signal weh add up cross pocket weh deh side by side.

Rollin sector
Fix border can split a hot arc between two sector an water it dung. Anodda way weh go wid it slide a window a k pocket roun di wheel, work out z at each a di 37 position, an look fi di highest one. Di highest a 37 z-score weh link togedda, pon a fair wheel, usually roun 2.2 to 2.5, suh a rollin-window maximum unda 2.5 a noise, an di level weh start get interestin higher too, roun 3.5.
