Treu's side lost to New Zealand in Dubai and to Fiji in South Africa, but the coach was satisfied ahead of the six remaining events.
"I think the team can be happy about being among the top three on the IRB rankings list after two tournaments," he told Die Burger.
"We lost but we were not annihilated.
"Of course the lads are not happy, because we had a good chance of winning both the first two tournaments.
"We lost to New Zealand in the Dubai semi-finals. Then Fiji beat us in the semi-finals in George. But they are the two best Sevens teams in the world at present and I do not think we were embarrassed.
"If you look at the countries that started building their teams two years ago, and you look at where we are now, there are many positives we can take from these two tournaments.
"The continuity we have now will certainly help us during the rest of the season," Treu explained.
Treu will now start preparing for the next two tournaments in the Sevens series.
"The guys will simply have to learn how to react in match situations; especially in a match such as the one against Fiji," Treu said.
"We must learn how to handle pressure in the last few seconds."
