Agree with all of the above, but it does say in the (EZY) ops manual that we are supposed to be on the localiser no faster than green dot (about 200kts) and the glideslope no faster than S speed (around 180kts).
Fully admit that it's possible to do 250 until 10-12 miles out, but a few pilots get a bit touchy if you're much faster than the ops manual guidance above.
With the 160-to-4 comment, again in the manual it says we should start slowing down 1 mile before that (i.e. 5DME for 160kts, 6DME for 170, 7DME for 180) in order to guarantee a stable approach.
