Charging LiFePO4 with different currents - Efficiency INSANE!

In today's battery test we will charge the 100Ah LioFePO4 cell with different charging speeds and see what the efficiency is, when we discharge it again. Will the efficiency decrease with higher charging current? Will the charge time half with double charge current? I also show you the efficiency of my battery since I installed it back in January.
