I think the just posted update on the US Sub-4:00 Milers Club has #591 and 592 and #593 and 594 transposed. Andrew Rafla and Obsa Ali (listed as 591 and 592) ran at the Sunset Tour Meet at Mission Viejo. The Sunset Tour results page lists the mile as being run at 8:00 p.m. The American Track League mile at which Isaac Updike and Liam Meiro ran their sub-4s, was run at 2:35 p.m.
