Turbulent Displace - Evolution slows down earlier than expected

layer Name: Displace Adj.

Effect Name: Turbulent Displace

This effect makes the edges randomly warp and move.

At 2 minutes & 36 seconds, the effect restarts and the effect is much slower.

I want the effect to continue warping the edges at the same speed for 5 minutes (ideally 10 minutes) then reloop back to the start.

I have tried a variety of Evolution Expressions but have been unsuccessful.

• If I configure the Evolution to loop back to the start at 2 minutes & 30 seconds, the effect works as expected and doesn't slow down.
  • (time - inPoint) * 210 % 31500
• If I configure the evolution to loop back to the start at 3 minutes, the effect slows down at 2 minutes & 36 seconds, but it does loop back to the start as expected.
  • (time - inPoint) * 210 % 37800

What am I missing that is causing the effect to slow down at 2 minutes and 36 seconds? Thanks!
