I use the curses-based "hte" ( sudo apt install ht ) to analyze and patch such binaries.
Run "hte your-executable", hit F6 and select eg the elf/image view and start analyzing or patching the annotated asm source.
Clean, minimal and served me well while solving [most of] such binary challenges

I just used a hex editor to change C7 45 F4 01 00 00 00 to C7 45 F4 0F 00 00 00...which increased the timer enough to allow for the calculation. Worked like a charm. :)
