Timestamp-Timing Lags

[u01ai11]

potential sources of lag that need to be addressed from experimental analysis perspective:

1. Between timer instantiation and the first mouse event

• This means our first sample will never have a timestamp at zero

2. From Blur initiation and hiding

• The timer and sampling from startTracking() are delayed whilst the blur is loading. If we have a promise that hides the screen, maybe best practice is to put startTracking in the promise.
