While normal slows stacks multiplicatively Rumble's Harpoon is special case:

"If the second taser slows an enemy that has been slowed by the first, the slow is refreshed and its movement speed reduction is doubled."

That means Kyubey X Eve is right. Double Harpoon at rank 5th and in Danger Zone slows you by 105% (practically sets your MS to 100). But the difference between Thresh's 99% and Rumble's 105% s when target has Boots of Swftness which reduces slow percantages by a quarter. So 99%=> 74,25% and 105%=>78,75%.
