After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the SNES native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 30 FPS for a total of 46526 frames or a Console Time of 25:50.863. First Frame set the frame before the Koopa disappears and End Frame set on the frame Bowser's hammers are invisible after touching the axe on 8-4.

I use Super NES Control Deck Model No. SNS-101 with a generic flashcart cartridge with "Super Mario Collection" ROM loaded and GV-USB2 Capture Card. Console check at the end of the run.
