 The full recursion program is not finished yet. Instead, we prove validity of a WHIR opening, with 25 variables, and rate = 1/4.
 
 ```console
-RUSTFLAGS='-C target-cpu=native' cargo run --release -- recursion
+RUSTFLAGS='-C target-cpu=native' cargo run --release -- recursion --count 8
 ```
 
 ![Alt text](docs/benchmark_graphs/graphs/recursive_whir_opening.svg)
 
+Detail: before 4 December 2025, only 1 WHIR opening was benchmarked. Starting from now, we prove a dozen of openings together (to be closer to the n-to-1 aggregation scenario) and we report the proving time / WHIR.
