Theatre Math - Rehearsal Disruption Index | Funny Theater Rehearsal Shirt | Stage Humor Tee | Scientific Theater Collection

📢 NEW DISCOVERY ALERT 📢

From the Institute of Applied Drama Science comes the Rehearsal Disruption Index — a mathematically sound explanation for why tonight’s run-through went off the rails.

B⋅Lα+ϕ=Em\frac{B \cdot L}{\alpha + \phi} = E_mWhere:

• B = Blocking (theoretically fixed, practically fluid)

• L = Lines (forgotten more quickly than learned)

• α = Attention (declines exponentially with phone use)

• φ = Phone Use (the true villain of modern rehearsal)

• Eₘ = Missed Entrance (the natural consequence of it all)

Ideal for stage managers, directors, and anyone who has ever whispered, “We’ll fix it in notes.”
