+<p>Here's a cool tip for more advanced users. Suppose you have an override running but you realize your overall insulin needs percent wasn't quite right. You can edit the override and force the <em><abbr title="With a capital L, Loop is one of several do-it-yourself artifical pancreas systems">Loop</abbr></em> app to recalculate the effect from the beginning of the override. A change in <abbr title="Insulin on Board, affects automated insulin delivery: the current active insulin (above or below the basal rate) that Loop calculates and uses for glucose prediction">IOB</abbr> may show up immediately when you edit insulin needs in the override. If you also quit and restart the app, this forces a recalculation from the beginning of the override.</p>
+<p>This is demonstrated in the following set of graphics contributed by a user - note the change in the <abbr title="Insulin Counteraction Effect - Loop models the expected glucose change based on carbs entered, absorption time and your settings; and adjusts based on measured glucose">ICE</abbr> graph for carbohydrates absorbed - this requires you to quit and restart the <em><abbr title="With a capital L, Loop is one of several do-it-yourself artifical pancreas systems">Loop</abbr></em> app. These examples are to illustrate what happens - typically the modification of insulin needs would be much smaller.</p>
+<p>The first graphic is where the Overall Insulin need value was dramatically decreased (user much more sensitive).</p>

+<p class="admonition-title">Example</p>
+<p>I set my biking override to be longer than my expected ride. When I return, I edit the insulin needs from 65% (needed while I'm actively biking) back to 100%. My negative <abbr title="Insulin on Board, affects automated insulin delivery: the current active insulin (above or below the basal rate) that Loop calculates and uses for glucose prediction">IOB</abbr> typically doubles at that change. I then disable the override and take the full negative <abbr title="Insulin on Board, affects automated insulin delivery: the current active insulin (above or below the basal rate) that Loop calculates and uses for glucose prediction">IOB</abbr> as a bolus. This helps prevents a post-exercise high that often follows my ride.</p>
+<p>I do not enter any carbs while biking and almost always ride first thing in the morning while fasting, so i just edit the override. I do not quit and restart the app.</p>

 <p>You can also use your <abbr title="a personal website used to view your glucose and diabetes management data, `Loop` can upload to `Nightscout`">Nightscout</abbr> site to activate/deactivate your <abbr title="With a capital L, Loop is one of several do-it-yourself artifical pancreas systems">Loop</abbr>'s override presets. To accomplish this, you will need to do some legwork as outlined on <a href="../../../nightscout/remote-overview/">this page for how to set up Remote Overrides in <abbr title="a personal website used to view your glucose and diabetes management data, `Loop` can upload to `Nightscout`">Nightscout</abbr></a> and you will need to be using a paid Apple developer account. Remote overrides require Apple Push Notifications service, and that is only available on paid accounts.</p>
