So much more goes into play with lane conditions. I will be happy to add to the confusion.
What I love about this game is that the more you know, the less you really know. I suggest to focus on good shot execution and using your eyes to give you feedback on what the lane is giving to you. Being aware of variables is important, but it is not as valuable as the information that you get from throwing a good shot for information later.
The following (in no particular order) are in play:
- Lane characteristics - variances in topography, lane wear, humidity, temperature, hardness, etc
- Lane Machine Settings (including the condition the lane machine itself it in)
- Type of conditioner used
- Type of cleaner/cleaner:water ratio
- Types of equipment/styles other players are using
- Dusting Procedures
Have fun.
