User blog comment:BonesMcGee/Brainstorm: Potential savings in using the hurry hatch trick/@comment-5405954-20121001213048

I did some math to update some of the calculations on this page. Running Average thru 09/30 is: 560 Eggs in 19034 Attempts = 33.99 Attempts / Egg, which is just about dead on the breakeven point. Other info: A Tier 1 Egg occurs 56.61% of the time. Tier 2: 29.82%. Tier 3: 12.32%. And the Phoenix about 1.25%. All tiers seem to occur around the same Attempts/Egg (between 30.5 and 36.5 Att/Egg). Corys are the most elusive, taking on average over 66 attempts to show up. Sabertooths show up quick (or not at all apperently) on average ony 17.2 tries. Surprisingly, the Tier 1 Oviraptor shows up the least often (only 3 times) (I expected a Tier 3 here). The Protoceratops (99x) and the Andrewsarchus (94x) are the most likely to appear. These 2 plus Dimetrodon, Wooly Rhino, and Kentrosaurus make up the overwhelming majority of the eggs reported thru this trick (70%), while 16 other dinos make up the other 30%.
