 ## DynamicISF (DynISF)
-DynamicISF was added in AAPS version 3.2 and requires you to start Objective 11 to use. Select DynamicISF in the config builder > APS to activate. It is recommended only for advanced users that have a good handle on AAPS controls and monitoring.

Select **Dynamic ISF** in the Config Builder > **AAPS** to activate. **Dynamic ISF** is recommended only for advanced users that have a good handle on their **AAPS'** controls and monitoring.

-DynamicISF adapts the insulin sensitivity factor dynamically based on total daily dose of insulin (TDD) and current and predicted blood glucose values. 
+**Dynamic ISF** adapts the user's insulin sensitivity factor (**ISF**) dynamically based on the user's:
 
-Dynamic ISF uses Chris Wilson’s model to determine ISF instead of a static profile settings.
+- Total Daily Dose of insulin (**TDD**); and 
+- current and predicted blood glucose values. 
 
-The equation implemented is: ISF = 1800 / (TDD * Ln (( glucose / insulin divisor) +1 ))
+**Dynamic ISF** uses Chris Wilson’s model to determine **ISF** instead of a user's static **Profile's** settings for **ISF**. 
 
-The implementation uses the equation to calculate current ISF and in the oref1 predictions for IOB, ZT and UAM. It is not used for COB.
+The **Dynamic ISF**  equation implemented is: ISF = 1800 / (TDD * Ln (( glucose / insulin divisor) +1 ))
 
-### TDD
-This uses a combination of the 7 day average TDD, the previous day’s TDD and a weighted average of the last eight hours of insulin use extrapolated out for 24 hours.
-The total daily dose used in the above equation is weighted one third to each of the above values.

+### TDD (Total Daily Dose)
+TDD will use a combination of the following values:
+1.  7 day average **TDD**;
+2.  the previous day’s **TDD**; and 
+3.  a weighted average of the last eight (8) hours of insulin use extrapolated out for 24 hours.
+
+The **TDD** used in the above equation is weighted one third to each of the above values.
 
 ### Insulin Divisor
 The insulin divisor depends on the peak of the insulin used and is inversely proportional to the peak time.
 For Lyumjev this value is 75, for Fiasp, 65 and regular rapid insulin, 55.
 
 ### Dynamic ISF Adjustment Factor
-The adjustment factor allows the user to specify a value between 1% and 300%. This acts as a multiplier on the TDD value and results in the ISF values becoming smaller (ie more insulin required to move glucose levels a small amount) as the value is increased above 100% and larger (i.e. less insulin required to move glucose levels a small amount) as the value is decreased below 100%.
+The Adjustment Factor allows the user to specify a value between 1% and 300%. This acts as a multiplier on the **TDD** value and results in the **ISF** values becoming *smaller* (i.e. more insulin required to move glucose levels a small amount) as the value is increased above 100% and *larger* (i.e. less insulin required to move glucose levels a small amount) as the value is decreased below 100%.

 ### Future ISF
 
-Future ISF is used in the dosing decisions that oref1 makes. 
-Future ISF uses the same TDD value as generated above, taking the adjustment factor into account. It then uses different glucose values dependent on the case:

-* If levels are flat, within +/- 3 mg/dl, and predicted BG is above target, a combination of 50% minimum predicted BG and 50% current BG is used.

 ### Enable TDD based sensitivity ratio for basal and glucose target modification
 
-This setting replaces Autosens, and uses the last 24h TDD/7D TDD as the basis for increasing and decreasing basal rate, in the same way that standard Autosens does. This calculated value is also used to adjust target, if the options to adjust target with sensitivity are enabled. Unlike Autosens, this option does not adjust ISF values.

+### CAUTION - Automations or Profile Percentage Increase
+**Automations** should always be used with care. This is particularly so with **Dynamic ISF**. 
+
+If **Dynamic ISF** is in operation, users should reconsider enabling any temporary **Profile** increase as an **Automation** rule or similarly activating a **Profile Percentage** which may create **Dynamic ISF** to be overly aggressive in correction bolusing and could cause hypoglycemia.
