I have done it a number of times and it is a fun dive and should be done so you have a half way stop and a lot of time at 20ft and 10ft for safety! Never had my computer go into deco! Even at 52 minutes as long as your accent is slow and takes the longest part of the dive! Here is video I shot in the Hole:

I agree with your assessment!
We dove the BH a year ago, and are in the process of planning our next trip to Belize, which will definitely including a return trip to the "Hole". I am often surprised by people who insist that if you go below 130' that they are immediately in deco, and have to shoot to a Safety Stop. My profile on the dive shows that while we did go to 140', and my computer did give me an "Ascent Time" (Cobra 2) warning for a 7 minute SS at minute 8 at a depth of 120', by minute 10, it had cleared, and that with an initial air charge of approximately 2800 psi, I finished the 27 minute dive with nearly 1300 psi, and all bars on the Tissue Saturation graph are green, and less than 80%. Average depth on the dive was 70', with a lot of time spent along the lip, watching the Midnight Parrots graze on the coral heads. We certainly could have spent a lot more time at both depth, and in the water, but the divemaster had us moving down and back relatively quickly, and there were non-divers on the boat, and out of courtesy, we surfaced earlier than we needed to.
I went behind the formations at depth, my wife stayed outside, and neither one of us experienced anything other than an enduring appreciation for that dive. It is amazing to experience the geology of the dive site, and appreciate the evolution of our planet, and the natural forces that have created that dive. My wife still raves about the numerous sharks that seem to circulate out in the center of the Hole, just out of harm's way (not sure if that is ours or theirs!).
For me, this is not a technical dive, it is pretty straight forward, and easily accomplished by an average diver (notwithstanding normal and expected diver self-protocols for comfort). I have to admit that I initially focused more on the darkness of the depth versus the clarity of the water and the experience of the dive, but once I oriented myself, from a techniques point of view, it was just another dive.
