The tilt of the bipolar magnetic region (BMR) is crucial in Babcock-Leighton process for generation poloidal field Sun. We extend work Jha et al. (2020) and analyze recently reported tracked BMR catalogue based on AutoTAB Sreedevi (2023) from Michelson Doppler Imager (1996-2011) Helioseismic Magnetic (2010-2018). Using information BMRs AutoTAB, we confirm that distribution bmax by not because are picked multiple times at different phases their evolution instead it also present if consider each only once. Moreover, find slope Joy's law initially increases slowly with increase bmax. However, when bmax>2.5 kG, gamma_0 decreases. decrease observed $gamma_0$ provides a hint to nonlinear quenching process.
