Package outline dimensions - meaning of theta and package identification
Just to be clear what you're asking about: 



The two rows in the dimension table are giving the min and max for each dimension. Theta can be between 0 and 7 degrees. D can be between 1.85 and 2.25 mm. Etc.

There is not necessarily any correlation between one dimension being near its min or max value and another dimension also being near min or max. For example, theta and D are probably not correlated.

On the other hand, others of the dimensions are likely to be correlated. For example, if theta is near 0 degrees, A1 might also be near its minimum value.
