$echo $(((8153228-386788-334276-5678272)/1024))
1712

-> it matches the 1710 used you see.

As for used/cached vs top/free -m, besides some rounding when dividing by 1024;
if you look at the -/+ buffers/cache line in free -m it more or less matches
the reported value.

It all accounts to what you want to display, if you want to take the
buffers/swap into account... displaying a "memory used" value is very empiric.
The original developer of systemload decided to compute the value this way...

If you take the values from top, and substract buffers and cached from 'mem
used' you end up with the same value.

$echo $(((7767120-5678292-334296)/1024))
1713

So.. not really a bug ?
