10m F2 or multi-hop Es?

KP2XX (6723km) spotted my 500mW WSPR at 1926z tonight. I think this was multi-hop Es. This is my best DX this summer on 10m WSPR. FK78ni is the British Virgin Is in the Caribbean. Apart from this spot, all other reports were from Europe. Still nothing on 6m WSPR here, given or received.

UPDATE 2125z:  I4ZTO (1185km) was still spotting me on 10m WSPR a few minutes ago.
