`sliding_*()`: Should `Total` reflect number of rows in analysis and assessment set combined?

Should total refer only to those observations used in analysis and assessment set?

library(rsample)
data("Chicago", package = "modeldata")

index <- vctrs::new_date(c(1, 3, 4, 7, 8, 9, 13, 15, 16, 17))
df <- tibble::tibble(x = 1:10, index = index)

sliding_window(df, lookback = 2, assess_stop = 2) |>
  get_rsplit(1)
#> <Analysis/Assess/Total>
#> <3/2/10>

sliding_index(df, index, lookback = 2, assess_stop = 2) |>
  get_rsplit(1)
#> <Analysis/Assess/Total>
#> <2/1/10>

sliding_period(
  Chicago,
  date,
  "year",
  lookback = 2,
  assess_stop = 1
) |> 
  get_rsplit(1)
#> <Analysis/Assess/Total>
#> <1074/366/5698>

Reproduce the examples for sliding_window(), sliding_index(), and sliding_period() and inspect the resulting Analysis/Assess/Total summaries. Compare the current Total values with the intended interpretation of observations in the analysis and assessment sets. Done means the behavior is clarified and consistently represented across these entry points.
