How accurately can I make this repeat until the statement is true?

So I am trying to experiment with cameras for a little intro, and everything is going fairly well except for at the end, at which point I want the camera to be focused back on the character. It sometimes works, but sometimes, especially if I open multiple tests at once, the camera will not revert back to the character.

Here's what I have. First, this sends the camera back to the character:

        workspace.CurrentCamera.CameraType = "Custom"
        workspace.CurrentCamera.CoordinateFrame = character.Torso.CFrame

Then, I tried to fix the times when it had an error by doing this:

if 
    workspace.CurrentCamera.CoordinateFrame ~= character.Torso.CFrame
    then repeat
        workspace.CurrentCamera.CameraType = "Custom"
        workspace.CurrentCamera.CoordinateFrame = character.Torso.CFrame
    until
    workspace.CurrentCamera.CoordinateFrame == character.Torso.CFrame
end

Sorry if it looks horrendous, I'm not experienced at all, so thanks for helping out!
