RE:Back to the 30s I think there could be a meaningful rise in SP if the Mcgill study shows promise with their tech. You have seen that with succesful news with other impairment detection companies as of late without revenues.
Also, I think an announcement of mass deployment (as they have alluded to is in the works) could also make it rise.
Long term I think you're right. They will have to prove they can make money with their different solutions just like any other company. 4 verticals to make money from so we should see them deliver on the revenue.
