Was just about to post this myself. The post split fixtures should have two midweek games, instead it's currently one midweek and 4 weekends. Meaning the last game is on 26/05/19 and the Scottish cup final gets pushed back to 01/06/19 which is far too late given some players in Scotland have contract's set to expire on 31/05/19. Scottish cup should be on the weekend of 26/05/18 and one extra split game should be played midweek. Date of final confirmed below.
ETA and as said above there is a massive gap between the last pre-split game and first post-split game. Usually there is only one free weekend then the post-split games start.
