Wins over Toulouse and Saracens secured a high seeding and home advantage in the Champions Cup knockouts, while victory against Leinster put them clear at the top of the United Rugby Championship. But Smith stressed previous promise didn't lead to silverware.
"Everybody realises home advantage is really a contribution to your campaign - it's not the start all and end all, though," Smith told BBC Scotland.
"We've proved that to ourselves as well. There's enough pressure on us to perform every week. The expectation grows and there's more unnecessary pressure on a simple decision-making process.
"For now, we want to win every collision. We want to win the lineout ball. We want to win on competitive scrum time. We want to score as many tries as possible. We want to avoid giving away tries. If that's the focus then the results will look after itself.
"But I do not want to burden the players or the environment with too many external uncontrollables because we've learned, if we're not going to learn from previous campaigns where we fell short because those type of conversations got into the mix, we must try and avoid that.
"Therefore, our mission is to focus on the controllables and let the race look after itself."
Smith revealed that Kyle Steyn is expected to resume running next week as he recovers from a suspected foot stress fracture, leaving him a doubt for the Champions Cup clash with the Bulls on 3 April.
There is still no clear timeline for Scott Cummings' return from a calf injury. Although Smith has not ruled Gregor Brown out for the remainder of the season, he confirmed the lock will not feature before Glasgow's trip to South Africa to face the Lions on 18 April as he continues his recovery from a hamstring injury.
