 Cloudflare calculates concurrent browsers as the monthly average of your daily peak usage. In other words, we record the peak number of concurrent browsers each day and then average those values over the month. This approach reflects your typical traffic and ensures you are not disproportionately charged for brief spikes in browser concurrency.
 
 ### How is billing time calculated?
-Cloudflare calculates usage on a daily basis. At the end of each day, we total all your **browser usage in seconds**. At the end of the billing cycle, we add up all the daily totals and convert them to browser hours. Billing is based on the total browser hours used during the month, with rounding only applied once at the end of the month (to the nearest hour).
+At the end of each day, Cloudflare totals all of your browser usage for that day in seconds. At the end of each billing cycle, we add up all of the daily totals to find the monthly total of browser hours, rounded to the nearest hour.
 
 For example, if you only use 1 minute of browser time in a day, that day counts as 1 minute. If you do that every day for a 30-day month, your total would be 30 minutes. For billing, we round that up to 1 browser hour.
