FTTC advice please

Anyone any good with lines stats who can tell me if these stats look right for the speed I'm getting (and also what type of cab it looks like I'm connected to from the band info?)
When I first went for FTTC I was expecting better connection speeds than what I got. Looking at the poles, etc I estimate I'm about 150-200m from the FTTC cabinet, and from there to the local exchange is around 400m for approx 600m total.
These are the line stats I'm getting.  Based on these stats would you expect a better speed or is the speed I'm getting looking correct for the stats/distance estimates above?

Re: FTTC advice please

To my comparatively untrained eye your attenuation (at the higher bands anyway) looks high for the distance you believe you are from the cabinet hence your speeds are low for that distance.
The band plan appears to confirm you're on an ECI cabinet.
