Calculate the SPI based on the below data:

BCWS $($PV$)$: $20$

ACWP $($AC$)$: $30$

BCWP $($EV$)$: $25$

Format your SPI as a numerical value using two decimal positions. For example, $1\mathrm{.}00$

Round down for $0\mathrm{.}004$ and lower and round up for $0\mathrm{.}005$ and higher

Do not use a percentage
