What does "as of block H" mean?

Every block.space figure names the block height it is synchronised to.

Every block.space figure is bounded by a block height. "as of block H" names the one block, H, that figures are synchronised to; where a ranking or the books sit at another height, pages name those too. A number without its height is not shown. The books stand at block 972,299 and the chain tip at 972,320 (as of block 972,315, 2026-10-20 12:10:25 UTC).
