	jjazeixUnsubmitted Not Done I think you should not base the accuracy on the width of the items but on the time +/- an error margin jjazeix: I think you should not base the accuracy on the width of the items but on the time +/- an error…
	amankumarguptaAuthorUnsubmitted Not Done This was the initial plan. But Animtim told that it may cause inaccuracies depending on different device's latency so it's not good to use time as a measuring parameter. Then we decided that we can use the position of note + width as the parameter. amankumargupta: This was the initial plan. But Animtim told that it may cause inaccuracies depending on…
