It's averaging to the right. If there is no cell to the right, the average drops. Lots of automotive tables use averaging. The trick is to make the last two columns on the right the same, then calibrate your throttle, adjusting the full throttle calibration up until full throttle ends up in the 90% column. That's it. 
Calibration walk through
Here is how to do it. Turn on your car without starting it. Plug the Procede cable into your laptop. Open Procede software, click on the red connect button to connect. Wait for current map to load. If you are going to continue using this map, proceed to next step, otherwise, click open to load the map you want to use. Wait for map to load. Click on the Analogue Inputs link on the left-hand column to open it. Click and drag it to the left, so you can see the readouts on the right, as shown in the pic. Calibrate the throttle by clicking on the "Set Throttle" button once, step on the throttle several times, take your foot off the throttle, click the "Set Throttle" button once again, step on the throttle several times, WHILE HOLDING THE PEDAL TO THE FLOOR, click the "Set Throttle" button once again, release the throttle. 

Now add about 50,+-5, to the Max Throttle field and click on the "Apply" button. Notice the Engine Load In % field changes with the throttle. Make sure that you add enough so that the "Engine Load In %" is between 92 and 93% when the throttle is pushed to the floor. Over 95% is too much, it jumps to the 100% column, under 85% is too little, it drops to the 80% column. 92.5% allows for some variance in the throttle calibration, but ensures full throttle is in the 90% column.

Notice this Procede map is rescaled, and the last two columns are identical. Also the first two columns and the bottom two rows are the same to allow for Throttle calibration variance. It kicks in very early and strong.
