Should I SFR an 18 Credit Points Unit?

Posting here instead of Reddit because I don't want to be slammed for being stressed about a potential 3.7 GPA.
My GPA has fluctuated between 3.8 and 3.9 for the three years I've been at Monash. I am currently taking a placement unit worth 18 credit points (3 normal units) and I'm pretty sure I will get a distinction in it because of my less than ideal in-semester evaluation grades by my supervisor and that they gave out only distinctions to the previous placement students  .

If I don't SFR, my GPA will drop to 3.7, but if I do SFR, it'll stay at 3.84. I still have quite a few units to study for (double degree) so just wanted to hear what people on this forum think. The cons of SFR is that this unit is a placement unit related to my industry, I'm not sure if it would look sus to future employers. On the other hand, it might be slight OCD but I'd like to graduate with a 3.8 GPA and if I don't SFR, I'd have to get all HDs for the rest of my units in the next couple of years in order to bring my GPA back to a 3.8 again, which I think would be hard to achieve.

Don't. You only get a max of 48 units to SFR through your degree so hold onto it until you really bomb out on a semester.
