Weave factor

The weave factor is a number that signifies the number of interlacements of weft and warp in a given repeat. It is also equal to average float and is defined as:

$M = \frac{E}{I}$

Where:

E is number of yarns per repeat
I is number of intersections per repeat of the cross yarn.

For example:

Cover factor for weave pattern (1) = 8/6 = 1.3

M (2) = 7/5 = 1.4
M (3) = 6/4 = 1.5
M (4) = 4/2 = 2
M (5) = 6/2 = 3

Question:

If you produce woven fabrics with these weaves with the same drawing in the warp and weft and using the same yarns, which weave pattern can be assumed to be loosest and which to be tightest respectively?

Pattern 1 because of lowest cover factor and pattern 5 because of highest cover factor?
Pattern 3 because of low cover factor, pattern 5 because of highest cover factor?
Pattern 5 because of highest cover factor, pattern 1 because of lowest cover factor?
Pattern 2 because of low cover factor, pattern 4 because of high cover factor?

Pattern number is assumed to be loosest.

Pattern number is assumed to be tightest.
