Why direct American aid understated support for Free Polish forces

Why did Free Polish forces appear to receive so little American Lend-Lease?

Because Britain supplied most of their equipment, while the table counted only direct American aid.

The displayed figures count American equipment, materials, and supplies assigned directly to each recipient. Free Polish forces appear low because most of their equipment came through Britain. That British contribution belonged to a different national account even though the troops fought in the same coalition. The answer warns against treating one supplier's table as a complete measure of what an Allied force received.
