The poly-linear borrow curve

Today's utilization sits exactly on a knot at 85% with a 4.41% rate. What is the borrow rate?

• The average of the knots on either side
• 4.41%, because at a knot the rate is the knot
• It can't be known without the next knot up

Two Kamino reserves both hold stablecoins. One has a knot at 95%. What does that tell you about the other reserve's curve?

• It also bends at 95%, because both are stablecoins
• It bends at 80%, Kamino's example floor knot
• Nothing; each reserve stores its own knots
