Iwer Sonsch | SM64: JRB pillar - Route idea for blindfolded Capless Cannonless Coinscoreless (done with sight) @iwersonsch5131 | Uploaded June 2022 | Updated October 2024, 9 hours ago.
The initial lineup should work fine by ESSing to the edge (I can't ESS on keyboard). After falling off the stone pillar once, you will have to turn a specific amount to the left and fall off a second time. Then you can framewalk up like I did at the end of the video.

Recently, Bubzia's chat saw the topic of 70 star CCC, and we concluded that it would be ridiculously infeasible if the run forcibly died the instant a coin is touched (Remember that in Blindfolded, you can't see whether you're in a slightly wrong position and about to touch a coin).
In addition, there are only 81 theoretically possible and only 72-77 RTA-viable stars, and the additional restriction of blindfolded gameplay would most likely put the challenge completely off-limits.

So instead, we came up with CCC*, with the C* meaning coinscoreless: Don't save a nonzero coin score, and you must save at 70 stars.
This means that a runner could hear that they accidentally collected a coin and simply exit the course, or they could reset the game if they hear a coin count up after collecting a star.
This variation also unlocks up to 6 red coin stars in side courses (BitDW, BitFS, WC, MC, VC, SA). However, collecting all 8 red coins in TotWC without a wingcap refill seems far off-limits for Blindfolded, and so the variation only adds 5 extra stars in practice.

Here's a spreadsheet estimating how much difficulty the CCC* challenge adds for each star in the game, excluding 100c stars for obvious reasons:
