A corrected LMC TRGB calibration on the HST photometric system yields M_F814W = -3.97 +/- 0.046 mag and raises the TRGB-based Hubble constant from 69.8 to 72.4 +/- 2.0 km/s/Mpc.

Consistent Calibration of the Tip of the Red Giant Branch in the Large Magellanic Cloud on the Hubble Space Telescope Photometric System and a Re-determination of the Hubble Constant
A corrected LMC TRGB calibration on the HST photometric system yields M_F814W = -3.97 +/- 0.046 mag and raises the TRGB-based Hubble constant from 69.8 to 72.4 +/- 2.0 km/s/Mpc.
