Change the formula: don't use an external constant, add a state. It's now the ratio between where the finger is at the first repeat and where it is now. Keep the repeat going when swiping into an other key. Currently only for arrows: It's now possible to go from an arrow to an other without waiting again for the key repeat timeout. The backspace and delete keys don't work well with this.
