Hi again from my side,
This weekend we did the tour: Planina Blato - Koča na Doliču, where we slept, then the next day from Dolič to Kanjavec, to Prehodavci and down the Valley of Triglav Lakes back to Planina Blato.
All snow patches are very small and passable.
As for the times, first day we hiked with all stops, snack and photographing approx 5h15min, second day from Dolič to Kanjavec 1h15min, from Kanjavec to Prehodavci 1h30min and from Prehodavci to Planina Blato 3.5h. Total 11.5h walking, similar to what you calculated, brett. Kilometers first day 15, second day 25, elevation gains first day +1300, second day +700. Still seems quite strenuous to me, at least for me, we hiked at a moderate pace, didn't rush. Definitely recommend sleeping somewhere in between, probably best at Doliču.
Safe steps
