I recently had good germination success with some ilama seeds. First i cracked open the seed slightly with some pliers, just enough to break the seal. I then soaked for about 10 hrs in a weak GA3 solution (eyeballed it but less than 600ppm). Rinsed and continued soaking in fresh water for another 10-12 hours. Stuck all the seeds in a big pot and have almost every one of those little guys coming up now after only 3 weeks!. I believe freshness of seeds is the biggest factor of germination success.
I had the same experience - I’m guessing 80% germinated.
I wiped the seeds down w peroxide-and then dried off. Used pliers to crack seed seal. Used ice cube tray w distilled water and Ga3 500ppm to soak- I weighted the seeds down w under a half inch stainless nut so they would stay submersed. I think the pos pressure of the water really pushes the GA3 in. I soak them until they won’t float. Then put them in promix that’s slightly moist, in a sealed Tupperware container , on a heat mat at 79 degrees. All that were going to germinate did so within 21 days.
