Hey there!
I was curious about trade rates, chest rates and success rates of various bastion routes (e.g. stables double triple vs triple to gap), so I made a small website to simulate bastion runs and determine a success rate based on some user-set minimum requirements.
I think this might be useful for comparing routes, testing the viability of new routes or checking if getting backup blocks is worth it. Each bastion has some presets that select the gold block and chest count for different routes, note that these may be different from how you do a route. Since I’m somewhat new to MCSR some of these might not be great default values so I’m open to any feedback.
To demonstrate how this website can be used I’ll show some of the experiments I tested. For my experiments I ran 500,000 simulations with ranked RNG and used 20 obsidian, 20 ender pearls, 3 fire res, 3 string and 5 explosives of any kind as the minimum requirements. Although a lot of players can do with less, this is what I would call a comfortable bastion leave at my skill level.
On housing, looting a double triple over a single triple increases the success rates from 63.8% to 81.5%, if you don’t loot the double chest at the bottom, the odds go down to 38.0% and 71.1% respectively (so looting the double chest makes a pretty big impact).
On stables, triple to gap (with both backups) has a 61.4% success rate, double triple only has a 30.3% success rate, and triple triple goes all the way to 84.1% success rate! It’s also interesting to see how much the ranked RNG actually helps, when simulating the stables routes on RSG rules, the routes go down to 27.2%, 12.3% and 58.2% respectively.
On bridge, the difference between ranked and RSG is even clearer since there is so much gold to trade. When looting a single triple on bridge, the success rate goes from 79.2% on ranked down to 33.7% on RSG.
On treasure, the default route gives around 62.4% success rate, to raise it to 95% you would need to get around 5 gold blocks and the treasure chest from bottom treasure!
The site also lets you see distributions for each of the items as well as an average yield, you can also test this out in the separate calculator tab if you just want to see those for some specified amount of gold trades or chests. It’s pretty fun to watch the distributions update live by lowering the update size in the simulation settings 
Feel free to try out the site and let me know if you have any questions, suggestions or cool experiments to share; I think it would be nice to test on actual bare minimum requirements and seeing how much those improve the odds but I dont feel qualified enough to make any experiments for these (as my bare minimums are probably worse than better players 
).
I have some other ideas for tools I want to try to make so hopefully I’ll be able to show those soon…
