 Every block on Flare, generated approximately every 1.8 seconds, initiates the selection of a sample of data providers to deliver the next feed update.
 This selection process leverages a stake-weighted verifiable randomness function (VRF), where the likelihood of each data provider being chosen is proportional to their stake.
-The expected sample size is one, and data providers have no control over, nor knowledge of, when they will be selected.
+The expected sample size (average) is `1.5`, and data providers have no control over, nor knowledge of, when they will be selected.
 
 In detail, each block has a unique seed value, used by FTSOv2 data providers to generate a personal random score.

 FTSOv2's block-latency feeds are designed to be statistically self-correcting.
 To further ensure their long-term accuracy, FTSOv2 uses the anchor feeds from [Scaling](/ftso/scaling/overview).
 Anchor feeds utilize a full commit-reveal process across all data providers with an inter-quartile range (IQR) band calculation, and update once every voting epoch (i.e. 90 seconds).
-Data providers are rewarded when the block-latency feeds remains within `±0.25%` of the anchor feeds every voting epoch.

   - Validators participate in consensus voting and are randomly selected as leaders to propose new blocks, weighted by their total stake (self-bond + delegated stake).

-Pre-configured Flare nodes are available on [Google Cloud Platform Marketplace](/run-node/gcp-marketplace-nodes).
-These nodes do not require installing dependencies or managing configuration files, they also come with a local database copy which can reduces bootstrap times.
