-I see that Mbe crit is below the minima of M(t). This is no doubt due to some SMALL round-off error somewhere in computing the total masses in the grid. If for instance, I use simply the formula above to find the mass of the BE sphere, it does not give me exactly what my code gives. The Visit calculation gives me ~0.78 whereas my code says it is ~0.72 -- in line with the Crit Mbe as expected.

 Now, it should also, be noted that the crit Mbe is computed by the formula:

 This describes __ blah blah, whereas my sphere is _blah Blah.
