How long does it take to lose 5% of excess arm fat?

I've been doing arm work outs that a Chinese fashion model taught me cause her father was friends with my father and she came to our Christmas party. It seems to be working cause when I wear old outfits that used to be tight around the arms, they seem looser in the arm area. I don't measure my arms since it's hard to measure your own arms due to ergonomic limits but I measure my legs and belly and I seem to be losing at a normal weight around those areas. My aunt also said I seem to be losing a lot of back leg fat which I do through voluntary muscle toning.
