Probably close enough…
Your distillate and crude have potencies that are below 100%. So you actually need to up the volume.
Eg for crude at 70% CBD, instead of 1200mg, you would use 12000/0.7 or 17140mg
For distillate at 87% CBD you’d use 12000/0.87 => 13790mg
You’ll also want to subtract that 17 or 14ml “addition” from your 120ml of MCT if you want your numbers to be on point.
Assuming your crude is decarbed, you also don’t need to heat or stir anywhere near that long. 10min should suffice.
