One question I’m asked very frequently goes something like: “Hey, I average X seconds, what do you think my time splits for Cross-F2L-OLL-PLL should be at this stage?”.
Firstly, it depends a decent amount on your current knowledge base - consider solvers A and B, who both average 20 seconds:
Solver A still inserts their cross pieces one at a time into the top layer and has extremely inefficient F2L, but knows full OLL and PLL and can execute these algorithms well. Realistically, the splits for this solver could look like 4-11-2-3.
Solver B has a much more move efficient F2L and has quite good lookahead ability, but still uses 4 look last layer. The splits for this solver could look something like 2-9-4-5, which is a vastly different profile to solver A.
Without being too pedantic, a better alternative question to “What should my splits be?” is “Based on my current splits of A-B-C-D and the current techniques and algorithms that I have learned, which step(s) of my solve can be improved most easily, or what should I learn next?”
This is a much simpler question to answer, and going to the effort to collect the data is the bulk of the work! (CSTimer.net has a nice way to do this - option - timer, multi-phase). Of course, most people probably don’t have a glaringly obvious phase of their solve which needs improvement, but it could be a useful exercise if you're a relatively inexperienced cuber without much of a sense of your strengths and weaknesses.
To assist with this, I’ve created a quick tool which allows you to enter your current CFOP solve splits and then compares them to average solve split times which I have put together - partially based on sub 10 solver data gathered in this speedsolving thread. When using this tool, I would suggest that you first reflect upon your solves without gathering splits data, as in the long term, self analysis and self awareness are going to push you much further than timing your splits and typing numbers into the spreadsheet. Then, use the tool to confirm your educated guesses about your own solving.
This tool won’t provide any magic solutions to improve those stages (that’s what the tutorials are for!), but may help you to identify a part of your solve which can be improved more easily than others. At that point, targeted practice on that stage is something to consider, if you think that your knowledge base is sufficient. For example, if you’re sub 20, know full PLL, but it is taking up 5 seconds in your solve, then deliberately practicing either your recognition or execution of those algorithms will be beneficial.
The sheet works for CFOP solvers between 60 and 8 seconds. Beyond sub 8, standard CFOP splits can become a bit difficult to measure, as solvers of that speed tend to frequently use things such as extended crosses, and various OLS techniques, so it’s not particularly relevant.
Let me know if you have any questions in the comments section. This short post is thanks to a member of the website who suggested that I cover this topic, thanks Omkar!
