Thats why I set mine at lightly because I'd really not want to overestimate and be over eating. That is why I don't reeat my exercise calories "I dont trust them to be exact" I will eat 25% maybe a bit more because I know that I burned at least that many. I researched "read" a magazine that talked about lowering as you went and psyched myself out lol. I will stick with what is working and "cross" that bridge when and if it happens
