Thinning Index Recommendation
>20 g/day Expect little or no response to normal rates of chemical thinners. You will need to thin more aggressively than normal
+ 20 to -20 g/day Expect normal thinning responses to standard rates of chemical thinners
-20 to -40 g/day Expect normal to slightly aggressive responses to standard rates of chemical thinners
-40 to -60 g/day Expect aggressive responses to standard rates of chemical thinners. Consider reducing rates to avoid over thinning
-60 to -80 g/day Expect very aggressive responses to standard rates of chemical thinners. Reduce rates to avoid over thinning
< -80 g/day Standard rates of thinners will result in severe over-thinning. Reduce rates by at least 50 percent.
Interpreting the MaluSim Model: look for three-to four-day trends
