Suunto really likes long surface intervals. If you have > 2 hours between dives then it will be a bit more liberal than GF High 85 on deep (30m/100ft) dives, and a bit more conservative in the 12-20 m range.
If your surface intervals are < 2 hours then it will be closer to GF High 70 for consecutive dives.
Main thing to look out for is that you might trigger a mandatory safety stop on the Suunto if you trigger the ascent warning. This can easily happen if you just move your arm up a bit too quickly.
