I had a Cedar Plank deck in Illinois, lots and lots of square feet, mostly off the ground some second story. I got lots of practice at rebuilding decks. I replaced all of it at least twice, some three times.
I finally ordered all of the USDA wood construction booklets for decks and piers and started building to their recommendations, spaced decking boards, gaps at board ends, supports spaced correct distance from the plank ends, etc. etc. Big improvement.
