    A couple of suggestions:

    • You can simply set the batchSize to 1 in the pagingConfiguration. With this you can reduce the number of times you use the index function. 
    • You can simply cast to an integer rather than getting the first element of the array, this removes another index.

    a!localVariables(
  local!list: { 67, 80, 100, 102, 150 },
  local!map: a!forEach(
    items: local!list,
    expression: a!map(number: fv!item)
  ),
  local!dataSubset: todatasubset(
    arrayToPage: local!map,
    pagingConfiguration: a!pagingInfo(
      startIndex: 1,
      batchSize: 1,
      sort: a!sortInfo(field: "number", ascending: false)
    )
  ),
  cast(
    typeof(1),
    index(local!dataSubset.data, "number", null)
  )
)
