ok ill put it simple, full hollow ichigo vs ulquiorra is not ichigos full power as it is him being controlled by his hollow side and therefore he isnt using his own max. power, probably zangetsus max, neither, it is not just "especulation" of how much reiatsu he has as the power is there, if it is divided into 2 parts that doesnt mean it isnt there just like the fact he cant use it doesnt mean it isnt there, i dont think you know more than unohana about measuring his reiatsu, but she said that ichigo while wearing less than half of what his bankai gave him was at captain level an then she said that then he had double considering that fact, she didnt measure his hollows reiatsu, neither was he using vizard mask, hollow powers or anything, it was just plain ichigo who had 2 times a captains reiatsu, in fact, she hasnt even seen him fighting as a vizard she cant have measured his hollow powers considering that fact, meaning ichigos total power is very high probably as much as i have stated i cant give an exact amount i cant sense reiatsu and less trough a computer but i know that if you add each others reiatsu it is around 4 times a captains
