Interesting how different the recommended targets are. I guess we're growing different crops, but wow... never thought anyone would be recommending pH in the 5's!
Here's mine from this spring:

So, you see the little table of recommendations at the bottom? Those are seasonal totals, and I break that into 5 applications. The break is not even, as different times of the year pull harder on one nutrient versus another, but the fertilizer manufacturers have that worked out pretty well by packaging the products you're using (pre-emergent, grub control, etc.) with the ratios that favor that time of the year. Usually you only have a choice of two different nutrient levels in each product type, making hitting those yearly totals like a 9 month long game of Tetris.
