property constants in elisp formulas

["Eddward DeVilla" <eddward@gmail.com>]

Hi,

    Is there a better way to do this?

  :PROPERTIES:
  :d_5: 0
  :h_5: 8
  :m_5: 16
  :d_4: 2
  :h_4: 18
  :m_4: 58
  :d_3: 6
  :h_3: 11
  :m_3: 33
  :d_2: 3
  :h_2: 13
  :m_2: 36
  :d_1: 0
  :h_1: 13
  :m_1: 59
  :d_0: 0
  :h_0: 6
  :m_0: 23
  :d_n: 17
  :h_n: 8
  :m_n: 59
  :END:

====================

Specifically, is there a better way to get at a property constant with
an elisp formula?  It seems the value is automatically put in parens
such that $h_3 is (11) which is a little awkward.  On the other hand,
maybe I can use that to store a list in a property.
