Our biggest benchmark is the WAP calculation.
Running it with the max values of x=99, y=512, z=512:

[runtimes/polimec/src/lib.rs:304] weights::pallet_funding::WeightInfo::<Runtime>::start_community_funding(99,
    512, 512) = Weight {
    ref_time: 425075813897,
    proof_size: 3531038,
}

This are the operational block weights defined in the Polimec runtime:

    operational: {
      baseExtrinsic: {
        refTime: 125,000,000
        proofSize: 0
      }
      maxExtrinsic: {
        refTime: 474,875,000,000
        proofSize: 4,980,736
      }
      maxTotal: {
        refTime: 500,000,000,000
        proofSize: 5,242,880
      }
      reserved: {
        refTime: 125,000,000,000
        proofSize: 1,310,720
      }
    }
    
  

We are dangerously close...

I can't officially approve since it's technically my PR, but it LGTM. Thanks for the weight comparison and the heads-up about the WAP calculation. Let's work on improving that now that we have a baseline weight/proof for comparison.
