I generally don't mind if there is a beat meter or not. I like to include one simply because it makes the stroke pattern not just audibly clear but visibly clear too. That said, if the beat sound is clearly distinguishable from the beat in the audio track and there are instructions on screen, then I can play no problem. I forget which one it was, but one CH had a meter that would fade in when a beat change occurred so you can visibly SEE the change and match it, then it would fade out again so you could focus on the video. May be worth a try?
In terms of difficulty, I am yet to play a CH video that I have been unable to beat (probably not on the first try lol). There are a couple that consistently bring me close to failing though. That said, there are a few that I turned off simply because I felt like I was just jacking for the sake of it. The material just didn't really trigger any kind of arousal. So I can safely say that I am much more on the side of being highly aroused, over simply jerking it furiously to a rapid beat just to force an orgasm. I play most CH videos with a Fleshlight, because it is significantly more intense and pleasurable than using my hand (which over the years has become a rather mundane method with which to masturbate lol). This creates an issue whilst playing some CH files; if the beats are overly complicated or super fast, I simply cannot keep up, even if I'm doing half beats. So long as the material turns me on, and the beat speed is maintainable, I'm a happy camper.
Then we turn to: "One man's trash is another man's treasure?" There have been a couple of CH videos that are filled with models I don't find attractive, fetishes that turn me completely off and/or other things I generally don't like and I could probably breeze through these. So whilst one person may be super turned on by that sort of material and blow their load in a couple of rounds, I could sit there and stroke all day to the point where I have a lousy orgasm and a dirty feeling about the material I just watched lol. So difficulty of a CH file is so hugely varied in many ways that someone may not finish the first round, others may make it to the end and have to go seek another video to finish them selves off. So I concur with BookGuy and Tittyluvr in regards difficulty. I'd rather be forced to blow through a combination of top material and creative (but relevant to the song) beat patterns to entice and excite me, rather than through dull repetition.
I can also attest to the amount of time it can take to make a CH video lol. I started EVO2 last October and I literally have only 3 rounds done, fucking full time jobs right.... Those 3 rounds combine to make around 50 minutes of playtime though lol and I am aiming for 7-8 rounds. (bit of a white lie) . I've been super picky on how my rounds play out. So much so that I have even remade just the instructional video 3 times. I kept all the old versions of the main rounds lol and they combine to over 72 minutes lol... some of the newer versions are completely different from the originals too (different song, beat meter...

) I may include these in a bonus download lol.
Onto Rendering a beat meter: It has become sort of second nature to me lol... I have all the settings I use memorised. It takes about 2 minutes for me to set up the project in After effects, then I hit "RENDER" and let it go. Go take a shower, play some Pokemon, walk the dogs (and play pokemon go too lol). Come back and BOOM! beat meter. This is the video that taught me how to render a beatmeter:

I adapted the way I generate a beat pattern for use in After effects since I dont have/use audacity, but that is exactly how I make my meters, bar a few tweaks in colour and sizes.
If you need someone to render some beat meters then I could possibly be of service. The only issue I would have on my end would be having the free time. I scarcely have time to work on my own project at the minute and it's driving me insane!! . I am however, off work from the 22nd of July for 11 days. So between some nerding out, working on my own CH and getting high/drunk... if you still need someone to make a beat meter I would be willing to help. I'll be sitting on my ass for most of those 11 days so, I dont mind setting it up to render then going to walk our two dogs for a bit
Literally all I would need is
1 - What colour(s) you want it. (haven't tried making a transparent one so that may be difficult...)
2 - How big you want it (In my last CH video it was 50px high and 1920px wide (width of the video))
3 - The raw beats file(s) without the music.
Either way I really look forward to the release.

Always happy to add new CH videos to my collection :D
