Two Fermentation Phase ABV Question

So I started a mead during the summer and had my primary. My SG was 1.053 and FG 0.996 which using gotmead.com ‘s ABV calc is around 7.82%.

I wanted to make it sweeter but also higher in ABV so I kinda rashly threw in a pound of honey and let it sit. After a month it started refermenting and has been for the past month. The new SG for that was 1.032 and FG as of today is 1.024 which using the same calc is around 1.15%.

Now, would it be wise to just add the ABV’s together for ~9% or would this mead just be the mystery ABV.

(I tried tasting it and it’s just sweet enough where it could anywhere between a 7-14 couldn’t tell you)

Thanks!
