Not in the context of what SG we are trying to achieve:

...."In Figure 3, we found that the benchmark requires a 1:8.6 twist to achieve the desired Sg of 1.4 at 2950 fps. Table 1 shows what happens to Sg if we keep the 1:8.6 twist and change other conditions. Notice that for higher speeds and temperatures, the Sg goes up. For lower speeds and temperatures, the Sg goes down. Decreasing barometric pressure and increasing humidity also make the air less dense. These things have the same effect as increasing temperature....."

You are thinking of minimum twist?
"Minimum twist required for an Sg=1.4. You may get away with slightly slower twist, but itís not recommended. Higher twist rates are generally ok."
