if you have more trouble routing with this PR, it might be worth just trying increasing the 120 and seeing what happens - as xo2 is slower than ecp5, the delay estimates and predictions may well need to be higher too

added higher value, but also made sure that we always use actual speed, so speed 5 is same for XO3 (where only 5 and 6 are available) and for XO2 ( where we have all speeds from 1 to 6)
