Tutorials better dropping

If want items dropped will this what I found out that help better so there be two different versions about it 

Old version  of dropped 

Random < 0,7  this old one it only by number  of 1 to 9 only 

New  version of dropped that made is this 

Global Random_Drop + Random 

Random < 0,025  in this is exactly like how Minecraft do dropped as also use in the Random number in scale of dropped in items by chance of 1 to 25 you even make higher 

If want to do growing tree will is is exactly like this how you have use this Global Random_Ticks + Random  then it growing tree very slow on time plus it also use day and night to grow tree by long ticks of normal Minecraft growing tree

Try it out it will work better I test out on my mod
