You are telling me it should converge then you seem to be telling him a discount should be expected.

Long before expiry: contango
Shortly before expiry: backwardation
At expiry: convergence, biased towards backwardation.

The relationship between future and underlying is not constant. The longer the time until expiry, the greater the chance of catching an upward spike, the shorter the time until expiry, the greater the chance of catching a downward drift.

...5 or 6 points sounds significant...

The VIX future has a multiplier of 10. Five points is the difference between eg 12.3 and 12.8, or $50/contract. Given the inputs to the pricing model have a maximum resolution of barely 10 cents, I don't think it's reasonable to expect a tighter match than that.
