You may not be doing anything wrong. I assume that your Qmax is 4400mAh. If so, FCC and RM will be less than 4400mA. FCC is based on Qmax, the Load Select, temperature and the Ra-table. RM will be a result of an OCV simulation, coulomb counting or it will set to FCC at charge complete. Something in the 3900mAh range could be realistic.
