Repeatability testing for the new manufactured heater fueling protocol
is looking pretty good in preliminary testing at the MHA lab in Quebec. Compare with
last year's testing with white birch and side ignition, below.Details here:
COV (coefficient of variation) is equivalent to repeatability, roughly +/- 25% in the graph above
