 ### Unparalleled performance
 
-When you hit *ENTER*, the next prompt appears instantly. There is never prompt lag when using
-Powerlevel10k: not when you work on Linux Git repository, or have 100,000 files in the current
-directory, or use Cygwin on Raspberry Pi, or enable 50 prompt segments that fill four full prompt
-lines on both sides of the screen. Powerlevel10k prompt is always blazingly fast, no matter what.
+When you hit *ENTER*, the next prompt appears instantly. With Powerlevel10k there is no prompt lag.
+If you install Cygwin on Raspberry Pi, `cd` in a Linux Git repository and activate enough prompt
+segments to fill four prompt lines on both sides of the screen... wait, that's just crazy and no
+one ever does that. Probably impossible, too. The point is, Powerlevel10k prompt is always fast, no
+matter what!

+Other Zsh themes capable of displaying the same information either produce prompt lag or print stale
+prompt that doesn't reflect the current state of the system and then refresh it later. With
+Powerlevel10k you get fast prompt *and* up-to-date information.
