HI Louis, the answer is yes. The way I would set this up is something like the following using the same disturbance type “All Fire” for all pathways. Note the values used for proportions are just examples.
Destination State Class | TST Min | TST Max | Proportion
[Post Surface Fire] | 0 | 14 | 1.0
[Post Surface Fire] | 15 | [Blank] | 0.5
[Post Mixed Fire] | 15 | [Blank] | 0.2
[Post Replacement Fire] | 15 | [Blank] | 0.3
Note that proportions will be respected amongst rows that meet the TST criteria for a specific cell. Because the 0-14 and > 14 conditions are mutually exclusive, this configuration would work fine. Within 15 years of a disturbance only surface fire is possible. After 15 years all three are possible and proportions add to 1.0.
