Is a parking method a good strategy to cross stitch a pattern with many single points?
For the pattern you posted, I would look at which stitches are rather close together, and 'hop' from island to island, taking a route so that the thread at the back doesn't form loops that are too large.
When there are single stitches or small groups that are further apart, I reason as follows: are the stitches/groups so far apart that it takes less thread to bind off and start again? If not, I make the thread go underneath one or two of some stitches in between (make sure it doesn't show at the front side, so don't push through completely), so the loops at the back side of your embroidery work are not that large.
If there are no stitches in between yet, you can always secure a large loop when you get there (with another colour).
