Favre fumbled 166 times in 302 games. You're good enough at math to easily see that Cousins is fumbling at a rate that leaves Favre in the dust.
Over his career. From 2000-2002 he started 48 games and had 35 fumbles. Dave Krieg also had 3 years where he started 40 games and had 40 fumbles. Warren Moon also went 40 fumbles in 47 games. Your historic rate, isn't so historic after all.
