Not that any sensible bookmaker -is there any other kind? - would install the Warriors as favourites to knock the reigning European champions off their perch on that basis alone, but the French side's record over the past two months does at least give the lie to the suggestion that invincibility is one of their defining traits.
Gregor Townsend will no doubt stress that point as he prepares his Warriors side for their trip to the south of France over the next few days. From his time with Brive and Castres, the Glasgow coach is well aware that French sides expect home wins as a matter of course, but anything that encourages the Glasgow players to believe that a notable smash-and-grab raid is achievable will be welcomed into the pre-match discussions.
"A lot of teams are rusty at this point in the season,"observed the Warriors head coach, I've watched a lot of French rugby, preparing for the Toulon game, and their rugby isn't very fluent yet. Defences are on top, and we're all trying to work out the scrums."
The consensus view of Glasgow is that they have kept up their run of victories without ever yet hitting top gear. There have been glimpses of their attacking potential - they produced one wondrous handling move during their 17-12 win against the Scarlets on Saturday that only came to grief when Sean Lamont ran out of support runners - but they have played only in fits and starts.
Still, five out of five is a record that no other PRO12 side can boast, one that has propelled Glasgow to the top of the Celtic/Italian table just as the European season gets under way. Along the way, Townsend has made use of 36 players, creating a level of internal competition that may not raise his hopes, but which certainly increases his options, ahead of Sunday's match in the febrile cauldron of the Stade Mayol.
"The players who have come in have performed well and taken their opportunities," said Townsend. "We know we are going to have to play close to our best to have a chance of winning. Just before our match on Saturday I watched Clermont play Toulon [Toulon won 25-19] and they are two of the best sides in Europe. But we can't wait. There are another two or three players who would like to be involved next week, so it will be as difficult to pick the team."
The most powerful influence on Townsend's earliest career was Ian McGeechan, and the Glasgow coach seems to have inherited something of the Lions legend's gift for analysing opposition sides. He also shares McGeechan's appreciation of the value of springing surprises. If he has spotted a weakness in the Toulon side - never the easiest task - then it is safe to assume that he has been hard at work cooking up plans to exploit it.
"We have spent a lot of time looking at both of our first European opponents,Toulon and Exeter," said Townsend. "We have some excellent players who are currently injured, like Ryan Wilson and Peter Horne, working [on analysis] with our coaches, and we have a lot of information on Toulon. We'll have a gameplan that we believe could lead to success.
"But you have to weigh that up against the quality of players that Toulon have, plus their home record, the atmosphere there, etc. What an occasion it's going to be.
"The 23 who get the opportunity to play will have deserved it because of the effort they have put in over the past five weeks. It's a privilege to have that opportunity to play. I was lucky in my career to have the chance to play there a couple of times. Their squad has grown since then into a real world club team, so it will be great to take them on."
When Glasgow pulled off their astonishing Heineken Cup win over Toulouse in France in 2009, there was a suspicion - flatly denied by the French side, of course - that Toulouse had been guilty of complacency and had underestimated their Scottish opponents. Glasgow's PRO12 position at the moment should be enough to discourage Toulon from doing anything similar.
Would Townsend not have preferred to slip under the radar ahead of Sunday's game?
"No," he said bluntly. "I'd rather be on five wins than two or none. Pressure to me is what comes from the opposition, their line-speed and how quickly they get on ball, not the outside influences.
"I don't know what it will mean to the media [that Glasgow are Pro12 leaders]. I don't know what it will mean to the Toulon players. I'm sure they will prepare well for us and look at our last few games. But it's just a great occasion to be involved in."
