Plenty of sources, you can also literally watch the new "fuse" ironman he is making for ToB and he explains and does a full opening of all his crates, post 99 and w/ leveled skills
e; also literally just googled this in 25 seconds
It is important to note that higher points does not improve the rewards; it simply gives players extra rolls towards the drop table. The player's skill level determines the rewards the player gets when opening the supply crate; high levelled players will get rarer materials, while lower levelled materials become less common the higher the player's level in that skill is. At the highest point, low levelled materials are removed from the drop table. While players with low levels in those skills can get rare materials, the drop rate is very low, but will increase with that skill level. According to Mod Ash, the herb, ore, fish, uncut gem, seed drops and logs are based on the player's Herblore, Mining, Fishing, Crafting, Farming and Woodcutting levels respectively.[2]
Because the rewards are determined when opening the crate[3], players can choose to keep them closed until their Herblore, Mining, Fishing, Crafting, Farming and Woodcutting levels are at a higher level, allowing players to receive rarer materials and supplies from the crate. Do note that supply crates do not stack in a bank; as such, storing too many supply crates may consume too much bank space.
