 .. option:: -mode=[latency|uops|inverse_throughput|analysis]
 
- Specify the run mode. Note that some modes have additional requirements and options.
+ Specify the run mode. Note that if you pick `analysis` mode, you also need
+ to specify at least one of the `-analysis-clusters-output-file=` and
+ `-analysis-inconsistencies-output-file=`.
 
- `latency` mode can be  make use of either RDTSC or LBR.
- `latency[LBR]` is only available on X86 (at least `Skylake`).
- To run in this mode, a positive value  must be specified for `x86-lbr-sample-period` and `--repetition-mode=loop`
-
- In `analysis` mode, you also need to specify at least one of the
- `-analysis-clusters-output-file=` and `-analysis-inconsistencies-output-file=`.
-
-.. option:: -x86-lbr-sample-period=<nBranches/sample>
-
-  Specify the LBR sampling period - how many branches before we take a sample.
-  When a positive value is specified for this option and when the mode is `latency`,
-  we will use LBRs for measuring.
-  On choosing the "right" sampling period, a small value is preferred, but throttling
-  could occur if the sampling is too frequent. A prime number should be used to
-  avoid consistently skipping certain blocks.
-  
 .. option:: -repetition-mode=[duplicate|loop|min]
 
  Specify the repetition mode. `duplicate` will create a large, straight line
