But with regular No.9 Greg Laidlaw rested for the visit to Kingsholm, Hart is looking to grab his chance in the spotlight with both hands.
"Yes, patiently and impatiently I've been biding my time," said Hart, who qualifies to play for Scotland through his grandmother.
"At the start I had a knee problem that the guys here were a bit concerned about and that set me back a couple of months. However, I did get a few club games.
"As a scrum half you always want to be organising, be accurate in everything you do and know structures inside out - that's what I hope to bring at Gloucester.
"I also enjoy the running side of things, looking for opportunities as well as getting stuck in physically. I like to make a tackle or two and give the big boys a rest if I can."
So far Hart has been restricted to just 17 minutes of action in the RaboDirect PRO12, but that was all he needed to get on the scoresheet with a try against Ulster Rugby last month.
"Being a half back you have to go into game with the team in mind, to ensure we go forward and that will be my focus," he told the Edinburgh Evening News.
"But I will be looking for those inside balls from the big forward runners, trying to snap up the offloads from running the fat man's track up the middle of the pitch."
