The probe was fine, it was an awkward cut so most of the bone was near the outside of one side. The estimated time seemed to become much more accurate once I hit the stall so it must only be using the time it takes to rise a degree over so many minutes. It eventually landed on what seemed to be a perpetual hour left mid stall so I don't think I'll be using the estimated time as any real measure. I didn't expect to anyway but as for the internal and pit temps, those were quite accurate so I'm pleased regardless. I hovered around 250-275, roughly 50m/lb
