One way you can read 100 all inclusive durood in just 2 minutes is that you read this durood once:



This durood includes the mention of "aalihi" and "baarik" and "sallim". Some buzrughs have said that durood without the mention of "aalihi" is devoid of full virtue and some have said durood devoid of the mention of "baarik" and "sallim" is devoid of full virtue. Durood should at minimum include all three mentions. So if this durood is read once and then followed up with 4 recitations of this durood:



So now 5 durood would have been recited and would have included mention of "aalihi" and "baarik" and "sallim" in an easy manner. If you read 5 per each groove on each finger you will read 20 durood per finger. 20 durood per finger for 5 fingers will give you 100 durood in roughly 2 minutes time. So if you read durood for just 10 minutes at this steady rate you will read 500 durood in just 10 minutes. *Disclaimer* This is according to my weak math skills!

Here is a picture of an index finger:



Count the top of the finger as 1 groove, then the 2nd groove before the knuckle groove, then the knuckle groove, and finally the 4th groove which is at the base of the index finger - 4 grooves per finger. 5 durood per groove. 20 durood per finger. 100 durood per hand in 2 minute time.
