General Questions

  1. I calculate a value of mi to be around 100 yet RocData limits mi to be between 1 and 50. Why?

  2. For the following three (sigma3, sigma1) laboratory strength data - (0,16), (5,105.9), (20,161) - why does RocLab 1.007, RocLab 1.006 and RocData 2.37 using Linear Regression and Simplex fitting give different values of mi and sigci when fitting the Hoek-Brown envelope?
