Clearly this isn't as fast as my 4 minute 28 second win (search YouTube for "TSK 20 in 4.5 minutes") , but I slowed down the IGT clock tick speed during gameplay as an additional aid to save reloads for that 4.5 minute win. So I don't think that time should count as a submission for IGT, because that additional aid makes it more of like a TAS (tool assisted speedrun), even though it isn't exactly. (Read the video description for more details about this sub-8 minute win.)
