I have received from wgt a response as to why the power bar carries on past where you hit stop, they said the following.
We are continuing to look into this issue further and hope to have a resolution soon. In the meantime, it seems that this meter jump is caused when the player is clicking on the outer edges of their device. Please try clicking more towards the middle to see if this helps.
I will give it a try.
I have received the exact same answer from WGT as well. I have recorded the swing meter both on my pc and my Ipad just bellow the pc screen then I started a 100% swing power at the same time on both devices and guess what ? The Ipad bar passes the Ding bar far ahead vs the pc swing bar.
To be fair, I had the pc screen set up at the minimum screen 1024x768 in order to get the shorter meter to compare whit the Ipad, otherwise in full screen mode, the pc meter would have take even more time to travel !!
On Ipad, it looks to me that when the green swing bar reaches the 1st vertical line before the Ding, it accelerates too much faster, the tempo seems unbalanced, too much unreal speed is reached in that blue pale zone. Thats what I thing the problem is.
