sounds like its not correctly seated at either end or has too tight a bend in it somewhere

Mine did that at low speeds too. Unplugged it from the speed and stuck it back in again which seemed to help a bit.

The nature of these speedos seems to be that they wander a bit anyway

sometimes when the cable breaks it sticks the nylon drive in box causing a flat spot which will result in the same symptoms

If you have fitted the new cable with to small a radius somewhere along its lenth then it will jump like you are describing, the inner cable catched on the outer causing the inner to get wound to a point that it  overcomes the friction between them then the lenth on the speedo end catches up causing the speedo to jump, its worse at low speeds.
If you dont fix it then you will get another chance to re route it shortly when it pops.
Or just use your satnav for MPH.

When mine broke I got a cheap Roadpilot gps camera detector from halfrauds. A nice big backlit accurate gps speedo and the added bonus of knowing where the fuzz like to hide on the back roads
