 ## CIP development progress
 
 ### Protocol specification completion
 
-- Completed comprehensive review of protocol overview, components flow, and parameters
-- Integrated votes and certificates specification into the CIP documentation
+- Completed a comprehensive review of the protocol overview, component flow, and parameters
+- Integrated vote and certificate specifications into the CIP documentation
 - Drafted node behavior and network specifications, including mini-protocol definitions
-- Advanced CIP towards completion with core protocol components fully specified.
+- Progressed the CIP towards completion, with all core protocol components now fully specified.
 
 ## Throughput metrics standardization
 
 ### Improved measurement methodology
 
 - Proposed transition from transaction-per-second (Tx/s) to transaction-bytes-per-second (TxB/s) metrics for enhanced comparability
-- Recommended using Tx/s only in introductory statements with transaction size context (e.g., "100 Tx/s with 1400 B transactions")
+- Recommended using Tx/s only in introductory statements with transaction size context (eg, '100 Tx/s with 1,400 B transactions')
 - Established TxkB/s and TxMB/s as primary throughput metrics for analysis
 - Benefits include:
   - Direct comparability across different transaction sizes
   - Clear nominal storage and network demand calculations
-  - Example: 100 Tx/s with 1400 B transactions = 140 TxkB/s = ~12 GB/day storage
+  - Example: 100 Tx/s with 1,400 B transactions = 140 TxkB/s = ~12 GB/day storage
   - Network overhead calculation: 140 TxkB/s × 10 peers = 11.2 Mb/s.
 
 ## Enhanced validation analysis
 
 ### Revised Cardano validation timing study
 
-- Completed refined analysis of Cardano mainnet validation times using clean dataset on idle machine
+- Completed a refined analysis of Cardano mainnet validation times using a clean dataset on an idle machine
 - Significantly improved accuracy over preliminary results by eliminating CPU contention effects
 - Updated findings for transaction signature verification and Plutus script execution:
   - Median times: 428.4 μs/tx and 211.5 μs/kB
   - Linear model: 148.1 μs/tx plus 114.1 μs/kB
   - Enhanced model: 137.5 μs/tx plus 60.2 μs/kB plus 585.2 μs/Gstep with Laplace error distribution
-- Results suitable for bulk block estimates despite individual transaction prediction limitations
+- Results are suitable for bulk block estimates despite individual transaction prediction limitations
 - Findings support reducing CPU-timing parameters in default Leios simulation configurations
-- Comprehensive analysis available in the [validation timing documentation](https://github.com/input-output-hk/ouroboros-leios/blob/main/analysis/timings/ReadMe.ipynb).
+- A comprehensive analysis is available in the [validation timing documentation](https://github.com/input-output-hk/ouroboros-leios/blob/main/analysis/timings/ReadMe.ipynb).
 
 ## High-throughput protocol validation
 
-### 1000 TPS Linear Leios demonstration
+### 1,000 TPS Linear Leios demonstration
 
-- Successfully demonstrated Linear Leios with transaction references supporting 1000 tx/s at 300 B/tx
-- Validated Stracciatella variant capability at 1000 TPS throughput levels
+- Successfully demonstrated Linear Leios with transaction references supporting 1,000 tx/s at 300 B/tx
+- Validated Stracciatella variant capability at 1,000 TPS throughput levels
 - Confirmed that Linear Leios with embedded transactions cannot sustain such throughput
 - Results provide clear protocol variant performance boundaries for high-throughput scenarios
