Moving an Object Forward Precisely


what I’m looking to do is very simple, but something I’ve been trying and for the most part failing to do for a couple days now. Basically, I have a Blueprint actor that I want to move 100 units along the X axis every 10 seconds in a smooth transition, always from its current position. What I have, shown in the images, works for the most part - my main issue is that the object moves forward only approximately 100 units - with the seemingly random value of -2.6. Unfortunately I need it to move exactly 100 or eventually everything goes wrong. If anyone could give me a hand, I’d be very thankful.
