well what unohana said had a lot of sense saying that half bankai left means half reiatsu left and that would be very specifically ichigos power is around double power and hollow ichigos power is always around ichigos max. meaning it is a pretty acurate and safe guess that his full power at this point should be around 4 times a captains at least that is the most secure scenario from what has been stated, altough like you said it still is unknown in an exact amount the only thing i can say its around the cuantity i have already stated but i cant be more exact, like you said is it yet to be seen but i am giving an aproximate that whe know exists and is not just pure especulation
