Yes and no; it completely depends on the micro-climates you are trying to create. With a design like this you can create different micro-climates in every bed, or you can repeat them to gain more production and ease of harvesting.

That greatly simplifies your irrigation infrastructure and allows you to use the cheap recycled-rubber soaker hoses that work fine with very low water pressure. Putting the paths on contour can also be a lazy way to create bioswales without extra digging.
I spend a lot of time doodling keyhole designs for various shapes of beds during boring meetings, etc., and I developed the following methodology for large areas that are accessible all around the outside:
1. Determine your standard reach. Most designs use a reach of 24" which results in 48" wide beds, but if your clients include children, etc. the reach may be different.
2. Find the least accessible point in the bed, usually the middle.
3. Find the point in the perimeter closest to the least accessible point.
4. The first path goes from this point in the perimeter, through the least accessible point, continuing to 48" (2*reach) from the other edge.
5. Starting from the opposite side of the bed, make the second and third paths 48" (2* reach) from the first path. Continue working out from the middle until the whole bed is accessible.
If there's another methodology that results in less path area than this one, I'd love to hear it!

I have tried to attach a photo but not sure if it took.
