Yes, there will be varying results with fibre-to-the-cabinet services. And with a speed test like that one, the performance of the whole chain is being tested, so your computer - for example - could bring the speed down if it's not working properly.
For what it's worth, I get 75Mb/s (77 burst) download, 18.4Mb/s (19.1 burst) from that test. If I ran it again, I'd expect to get different numbers.
My sync speeds are currently 79.2Mb/s download, 20Mb/s upload. Usually the download speed sits at the full 80Mb/s, but slight variations are to be expected. I'm about 200 metres from the green cabinet as the crow flies - no idea of the actual route the cable takes once it reaches the pole in the neighbours garden. My router draws pretty pictures of the frequency response of the cable between me and the green cabinet, and I can see a dip in the 1.2MHz region, implying that the cable is not perfect in some regard. Often this is caused by a repair in the pre-DSL days, which introduces reflections. It's a real shame that I didn't have this router back in the day when I tripled my ADSL speed by making two changes to my wiring - it would have been really interesting to see the effect of my wiring problems on the frequency response.
Anyway, the sync speed is the low-level data rate negotiated between my router and the DSLAM in the green box. So the overall throughput, as measured by an internet speed test, will never be as high as that.
Speeds in the 2Mb/s region might well seem OK, but that's a long way away from 30Mb/s. If I was only getting 1/15th of what I was paying for, I'd want to know why.
