Algorithm Reasoning
ISF vs Blood Glucose — Current Settings V1 V2

Lower ISF = more insulin per mg/dL of BG error. Both curves assume current TDD and normal target setting. The vertical line marks your current BG.

── V1 ISF at BG ── V2 ISF at BG ── Profile ISF
Sensitivity Ratio vs BG

Ratio = Dynamic ISF ÷ Profile ISF. <1.0 = more aggressive than profile. >1.0 = more conservative.

── V1 ratio ── V2 ratio ── 1.0 (= profile)
SMB Size vs BG (at current basal & settings)

Estimated microbolus across the BG range. Caps and IOB limit are applied. Assumes BG = eventual BG (simplified).
