Are you sure that the reading were 20-30 percent off and not just delayed? Libre and other sensors measure sugar level in the extracellular fluid and it takes some time before glucose gets there from blood.
The delays make the comparison difficult. Also if it gets too high or low then people react and quickly change the slope of the graph, then the sugar level in the extracellular fluid would not reach the same extremum as the sugar in the blood.
