actual split in terms of consumption is probably not 25/75.</span></div><div class="yiv2938415079MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri", "sans-serif"; font-size: 11pt;'> </span></div><div class="yiv2938415079MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri", "sans-serif"; font-size: 11pt;'>Do you have any excess air measurements (or O2 measurements) taken with a combustion analyser between the stove and the outer edge of the pot?
