	var
	last = start+count-1
	if start > ben.chain.latestNumber:
	# requested range beyond the latest known block
	return
	if last > ben.chain.latestNumber:
	last = ben.chain.latestNumber
	# get bodies from database
	for bn in start..ben.chain.baseNumber:
	let blk = ben.chain.blockByNumber(bn).valueOr:
	result.add Opt.none(ExecutionPayloadBodyV1)
	continue
	result.add Opt.some(blk.toPayloadBody)

It calculates this last payload body to fetch but ultimately that doesn't matter, it fetches all of start..ben.chain.baseNumber, which could be arbitrarily more more than the maxBodyRequest == 32 intended.
