MFP Maintence Calories Inaccurate?

Malvarez2013

So, I am a lightly active 21yo 130lb female and MFP has my maintence calories set to 1830. However, on many other sites (as well as by calculating my TDEE by handwriting formulas), my maintence calories are always set between 2100-2300. Has this happened to anyone else? Has anyone had personal experience keeping with their maintence calories and gaining/losing weight?
