Can’t tell if the list is lagging (seems sort of like it) but the order is not correct. In the picture below A.Sato (me, in blue) is ahead of R.Ruyack (rider in black). In the list the order is reversed.
At one point I caught R.Ruyack (we were riding together) and on the right the gap said 10 seconds and I was passing him.
Just completed a ride and I noticed exactly the same thing. As you say, sort of laggy but not quite. I had one rider who overtook me and stayed a couple of metres ahead for quite some while but he continued to stay behind on the listing. I had to slow down basically to re-arrange the order correctly.
