Why a second filter changes the answer. The October 2026 cube holds one dimension at a time, so a count for Internet Marketplace Platforms on its own is read straight out of it and is exact. Combine Internet Marketplace Platforms with a second dimension and the cube has no such cell — the explorer estimates it, shows the ceiling it cannot exceed, and labels it an estimate rather than passing it off as a measured number.
