While on short final (on a zero wind day) see if you can pitch for 60 --- in a sense you are slowing it up a bit more before you get to the round-out part.
Primarily for the OP, who is trying to break the code:
If you only pitch, you most likely will leave the desired profile. How about pitch and/or power for 60? Both influence and control airspeed and profile to one degree or another. Fast, slow or on 1.3 Vso, the means to correct/maintain may depend more on one that the other. Blend the two, with more of one than the other depending on the situation of current speed, weight, turbulence, downdraft/updraft, etc. When really slow, it is possible (and preferable) to flare with power.
Pitch alone doesn't always control airspeed on final. Its only simple after a lot of practice.
Consider moving the seat height up or down (if possible) for a sight picture that suits you, and scan from the nose to the end of runway or horizon until you find your sweetspot to judge flare height and flare control.
Configure earlier, trim and stabilize the speed for more accurate landings. This is especially important when in the backcountry when normal patterns/circuits are not possible due to terrain/obstructions at different airports. This works even at same-same, cookie-cutter, flatland airports. A good landing begins early in the approach. Good luck.
