✱) Disclaimer
This service is non-official, and it is not related with Topcoder company. Workload and earning estimates are based on public data available from public Topcoder APIs, and they might be incomplete and erroneous. In particular:
- Member records include only challenges (i) in which selected member won a prize superior to $100; or (ii) which were copiloted by the member. All first=to-finish challenges are deliberately excluded from the records. Most of data science challenges (Marathon and Single Round Matches) are missing in the records, because they are not reported by the public Topcoder API used by this service (with exception of very recent Marathon Matches).
- Some records are manually added / corrected for selected members, e.g. to include Topcoder Open victories into results.
- The time spent by member on competing (copiloting) is estimated as the overall runtime of corresponding challenges included into this member's records. The runtime of a challenge is calculated from the challenge registration start to its submission deadline. If several challenges from member records were running on the same day, that day is counted only once. Overall, this is a very rough estimation of member worktime, which may be very different from the actual time/efforts spent by a member on its challenges.
- Total earnings from competing are estimated as a sum of prizes won by selected member in the challenges included into his records. The public Topcoder API does not disclose the actual copiltoing payments received by copilots for each challenge, thus to estimate copiloting earning we assume the standard $600 copilot payment for regular-size challenges, and $5000 payment for Marathon Matches.
- The effective hourly rate is estimated as the total competing (copiloting) earnings divided by 1/3 of estimated time spent by member on copiloting/competing (because the competing/copiloting time estimates are done as the total runtime of a challenge, and do not factor in ~8h out of 24h workday).
Overall, the absolute estimations of workload, earnings, and effective hourly rate should be taken with a grain of salt; however, these estimations should be adequate to compare relative earnings and workload of different members.
